A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?

Answers

Answer:

0.706 L (Liters)

Explanation:

P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X

T1 T2 290 K 273 K

706 mL = X

The increased volume will be "706 L".

According to the question,

Pressure,

Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]

Temperature,

Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]

Volume,

Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]

By using the Boyl's and Charl's combination law, we get

→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]

or,

→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]

By putting the values, we get

→      [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]

→      [tex]= 706 \ L[/tex]

Thus the aforementioned answer is right.

In the laboratory you dissolve 12.7 g of silver fluoride in a volumetric flask and add water to a total volume of 125. mL. What is the molarity of the solution?​

Answers

Answer:

Molarity = 2.4 M

Explanation:

Given data:

Mass of silver fluoride = 12.7 g

Volume of water = 125 mL (125 mL× 1 L /1000 mL = 0.125 L)

Molarity of solution = ?

Solution:

Number of moles of silver fluoride:

Number of moles = mass/molar mass

Number of moles = 12.7 g/ 41.98 g/mol

Number of moles = 0.30 mol

Molarity:

Molarity = number of moles of solute / volume in L

Molarity = 0.30 mol / 0.125 L

Molarity = 2.4 M

What did Antoine Lavoisier’s experiments demonstrate?
A. Atoms always split into pairs during a chemical change.
B. Mass is neither lost nor gained during a chemical change.
C. Matter can be created during a chemical change.
D. Energy is neither lost nor gained during a chemical change.

Answers

Lavoisier disproved the phlogiston theory. He demonstrated that there was an element called oxygen that played a major role in combustion. He also showed that the mass of products in a reaction are equal to the mass of the reactants. In other words, no mass is lost in a chemical reaction.

Calculate the mass of 4.55x1024 molecules of sucrose

Answers

Answer:

2584 g

Explanation:

The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.

First we convert molecules into moles by using Avogadro's number:

4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 mol

Now we convert moles of sucrose into grams, using its molar mass:

7.55 mol * 342.3 g/mol = 2584 g

What is the volume of a 492.2g sample of Kr gas?
0.007601 L
131.6 L
5.870 L
21.97 L

Answers

Answer:

131.6 L

Explanation:

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, the correct option is option B that is 131.5l. There is no force of attraction between the particles.

What is ideal gas equation?

Ideal gas equation is the mathematical expression that relates pressure volume and temperature. Ideal gas is a hypothetical gas. Vanderwaal behave as ideal gas at high temperature and low pressure.

Mathematically,

PV=nRT

where,

P = pressure=1 atm

V= volume=?

n =number of moles=given mass/ molar mass

                                =  492.2/ 83.79

                                = 5.87 moles

T =temperature = 273K

R = Gas constant = 0.0821 L.atm/K.mol

1× V = 5.87 × 0.0821 L.atm/K.mol × 273 K

V =131.5l

131.5l is the  volume of a 492.2g sample of Kr gas.

Therefore, the correct option is option B that is 131.5l.

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass

Answers

answer: 11,200 g

step by step explanation:

D= M/V
M= DV
M= (13.6 g/cm^3) (825cm^3)
M= 11,200 g

The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.

What is density ?

Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.

Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.

Give that, volume of the object = 825  cm³

density =  13.6 g/cm³

Mass = volume × density

m = 825  cm³ ×  13.6 g/cm³ = 11220 g

Therefore, the mass of the object is 11220 g.
