Explanation:

A sample of sulfur dioxide occupies a volume of 6052 mL at 352 K and 892 mm Hg. What volume will the sulfur dioxide occupy at STP?

Answers

Answer:

5511.99 mL

Explanation:

Given data

Volume V1= 6052 mL

Temperature T1= 352K

Pressure P1= 892 mm Hg

At STP the parameters of gas are

Temperature T2= 273.15 K

Pressure P2= 760 mmHg

Applying the gas equation

P1V1/T1= P2V2/T2

Substitute to find V2 we have

892*6052/352= 760*V2/273.15

5398384/352= 760*V2/273.15

15336.31= 760*V2/273.15

Cross multiply

15336.31*273.15= 760*V2

4189113.0765= 760*V2

4189113.0765/760= V2

V2= 5511.99 mL

Hence the volume at STP is 5511.99 mL

What is the amount of moles of NaOH, if the solution molarity is .33 M NaOH in 0.75 L solution

Answers

Answer:

The amount of moles of NaOH is 0.0495

Explanation:

Molarity is a measure of concentration that is defined as the number of moles of solute that are dissolved in a given volume.

In symbolic form molarity is presented as:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case:

Molarity= 0.33 MNumber of moles of solute= ?Volume= 0.75 L

Replacing in the definition of molarity:

[tex]0.33 M=\frac{number of moles of solute}{0.75 L}[/tex]

number of moles of solute= 0.33 M* 0.75 L

number of moles of solute= 0.0495 moles

The amount of moles of NaOH is 0.0495

Answer:

0.248 moles of NaOH

Explanation:

Concept of Molarity is mol/L

[x] = 1 M

1 mol of x contained in 1 L of solution. We write molar concentrations between []

M = mol/L then M . L = mol

Our solution is NaOH

0.33 M . 0.75L = mol

This solution contains 0.248 moles of NaOH

Calculate the freezing point of a nonionizing antifreeze solution containing 388 g ethylene glycol, C2H6O2, and 510 g of water.

Answers

Answer:

T° freezing solution = -22.8°C

Explanation:

To solve this problem we apply, the Freezing Point Depression. This is a colligative property which its formula is:

T° freezing pure solvent - T° freezing solution = Kf . molality . i

i = Van't Hoff factor.

We have been informed is a nonionizing solute, so i = 1

Our solute is ethylene glycol, so le'ts determine the moles to get molality

388 g . 1 mol / 62.07 g = 6.25 moles

molality (m) = moles of solute /kg of solvent

We convert mass of solvent, water, to kg → 510 g . 1kg /1000g = 0.510 kg

6.25 mol /0.510kg = 12.25 m

We replace at formula → 0°C - T° freezing solution = 1.86°C/m . 12.25 m . 1

T° freezing solution = -22.8°C

What is the molarity of 5.60 mol of sodium carbonate in 1500 ml of solution?

Answers

Answer:

3.74 M

Explanation:

We know that molarity is moles divided by liters. The first thing to do here is convert your 1500 mL of solution to L. There's 1,000 mL in 1 L, so you need to divide 1500 by 1000:

1500 ÷ 1000 = 1.50

Now you can plug your values into the equation for molarity:

5.60 mol ÷ 1.50 L = 3.74 M

according to the periodic table, which two elements have an atomic mass less than twice their atomic number?

Answers

Answer:

Hydrogen and Oxygen

Explanation:

Hydrogen atomic mass = 1.008 amu

atomic mass = 15.999 amu

According to the periodic table, two elements whose atomic mass is less than twice their atomic number are hydrogen and oxygen.

The atomic number of an atom refers to the number of protons in that atom. It serves as an identity for atoms of elements. The atomic mass of element is the weighted average of the masses of all the isotopes of the element.

The atomic number of oxygen is 8 while the atomic number of hydrogen is 1. The atomic mass of oxygen is 15.999 amu while the atomic mass of hydrogen is 1.0008 amu.

We can see that twice the atomic number of oxygen gives sixteen while twice the atomic number of hydrogen gives two. Therefore, two elements whose atomic mass is less than twice their atomic number are hydrogen and oxygen.

Explanation:

The excessive pumping of water through well is the major reason for the drop of ground water level. The nearby farms over use water and pumps from undergrounds.

What is underground water?

Water beneath the earth surface is called ground water. The storage of ground water is a very important in all areas to sustain our need for water and it must be maintained pure without the presence of overdose of heavy metals and other impurities.

Reduction in the level of ground water storage is a serious issue that might leads to a scenario where the drinking water is not sufficient. The uncontrolled use of pump water by factories, industries and farms results in the drop of ground water level.

The nearby farms might pumping water from sources uncontrollably in the area. That is the main reason of dropping in ground water level. Hence, option B is correct.

The formula is m1v1=m2v2

Answers

Answer:

8. 171074.8 mL

9. 3475 mL.

Explanation:

8. Determination of the volume of the diluted solution.

Initial Molarity (M₁) = 14 M

Initial volume (V₁) = 523 mL

Final Molarity (M₂) = 0.0428 M

Final volume (V₂) =?

Using the dilution formula, we can obtain the volume of the diluted solution as follow:

M₁V₁ = M₂V₂

14 × 523 = 0.0428 × V₂

7322 = 0.0428 × V₂

Divide both side by 0.0428

V₂ = 7322 / 0.0428

V₂ = 171074.8 mL

Therefore, the volume of the diluted solution is 171074.8 mL

9. Determination of the volume of water added.

We'll begin by calculating the final volume of the solution. This can be obtained as follow:

Initial Molarity (M₁) = 3.2 M

Initial volume (V₁) = 973 mL

Final Molarity (M₂) = 0.7 M

Final volume (V₂) =?

M₁V₁ = M₂V₂

3.2 × 973 = 0.7 × V₂

3113.6 = 0.7 × V₂

Divide both side by 0.7

V₂ = 3113.6 / 0.7

V₂ = 4448 mL

Thus, the final volume of the solution is 4448 mL

Finally, we shall determine the volume of water added. This can be obtained as follow:

Initial volume (V₁) = 973 mL

Final volume (V₂) = 4448 mL

Volume of water added =?

Volume of water added = V₂ – V₁

Volume of water added = 4448 – 973

Volume of water added = 3475 mL

L•atm/mol K
L•atm/mol · °C
mL • atm/mol. K
L• kPa/mol - K

Answers

Answer:

A. L•atm/mol K

Explanation:

The ideal gas law equation is given as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant

T = temperature (K)

As rightly stated in this question, R is the ideal gas constant, which can be different depending on the unit of the other components.

At STP;

V = 22.4L

P = 1 atm

T = 273 K

n = 1 mole

Hence, using PV = nRT

R = PV/nT

R = 1 × 22.4/1 × 273

R = 22.4/273

R = 0.08205

Approximately, R = 0.0821

With the units of P as atm, V as L, n as mol and T as K; R will be 0.0821 L•atm/mol K

Calculate the number of molecules in a 45.6 gram sample of C2H4.

Answers

Answer: The number of molecules in a 45.6 gram sample of [tex]C_{2}H_{4}[/tex] are [tex]9.78 \times 10^{23}[/tex].

Explanation:

Given: Mass of [tex]C_{2}H_{4}[/tex] = 45.6 g

Molar mass of [tex]C_{2}H_{4}[/tex] is 28.05 g/mol.

Therefore, number of moles of [tex]C_{2}H_{4}[/tex] are calculated as follows.

[tex]No. of moles = \frac{mass}{molarmass}\\= \frac{45.6 g}{28.05 g/mol}\\= 1.62 mol[/tex]

According to the mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules. Hence, number of molecules present in 1.62 mol are calculated as follows.

[tex]1.62 \times 6.022 \times 10^{23}\\= 9.78 \times 10^{23}[/tex]

Thus, we can conclude that the number of molecules in a 45.6 gram sample of [tex]C_{2}H_{4}[/tex] are [tex]9.78 \times 10^{23}[/tex].
