What is concentration of sugar solution if 20 gram is dissolved in enough water to make the final solution upto 2 Litre?

Answers

Answer 1

Sugar solution has a 0.03 mol/L concentration.

What exactly is soluble?

In chemistry, the term "solubility" describes a material's capacity to dissolve in another substance (the solvent). The solute's inability to create such a solution is known as insolubility.

The amount of a solute in a saturated solution, or a solution in which no more solute can be dissolved, is typically used to gauge how soluble a substance is in a given solvent. The two compounds are said to be in balance for solubility at this time.

Sugar's molar mass equals 342g/L

Number of solute moles = 20/342 = 0.0584 moles

Molecularity = 0.0584

20

1. molarity = 0.03 mol/L

How many particles are in a 151 g sample of Li2O?

Answers

Answer:

3.052 × 10^24 particles

Explanation:

To get the number of particles (nA) in a substance, we multiply the number of moles of the substance by Avogadro's number (6.02 × 10^23)

The mass of Li2O given in this question is as follows: 151grams.

To convert this mass value to moles, we use;

moles = mass/molar mass

Molar mass of Li2O = 6.9(2) + 16

= 13.8 + 16

= 29.8g/mol

Mole = 151/29.8g

mole = 5.07moles

number of particles (nA) of Li2O = 5.07 × 6.02 × 10^23

= 30.52 × 10^23

= 3.052 × 10^24 particles.

The answer is Option B, NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

What is an Acid Base Titration ?

An acid–base titration is a method of quantitative analysis.

It is used for determining the concentration of an acid or base by neutralizing it with a standard solution of base or acid of known concentration.

An indicator is used to monitor the progress of the acid–base reaction.

Ascorbic acid, HC₆H₇O₆ is an acid. So can be titrated with a base , sodium hydroxide, NaOH using the indicator, phenolphthalein.

HC₆H₇O₆(aq) + NaOH(aq) → NaHC₆H₇O₆(aq) + H₂O(l)

Among the options , HCl is an acid , LiBr , CaCl₂ are salts , NaOH is the only base.

Phenolphthalein changes from colorless to pink (or red) when all of the acid gets neutralized.

Therefore NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

What is the mass in grams of 9.02x10^28 atoms of Fe​

Answers

Answer:

83.674 grams of Fe

Explanation:

9.02 x 10²⁸ atoms

To convert from atoms to grams, we first need to convert atoms to moles. To do this, divide the atoms by Avogadro's Number, 6.02 x 10²³

9.02 x 10²⁸ ÷ 6.02 x 10²³

= 1.498 moles of Fe

Now we need to convert moles to grams. To do this, multiply the moles by the molar mass of Fe. The molar mass can be found on the periodic table.

1.498 • 55.845

= 83.674 grams of Fe

A gas has a volume of 5.00 L at 20 degrees Celsius. What is the volume of gas at 150 degrees Celsius.

Answers

Answer:

7.22 L

Explanation:

From the question,

Applying Charles law,

V₁/T₁ = V₂/T₂...................... Equation 1

Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin

Make V₂ the subject of the equation

V₂ = (V₁×T₂)/T₁................. Equation 2

Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K

Substitute these value into equation 2

V₂ = (5.00×423)/293

V₂ = 7.22 L

Answers

Answer:

Due to warm temperature.

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.
