Chapter 11, Problem 11.55SP

(a)

Interpretation Introduction

Interpretation:

The molality of given citric acid solution has to be calculated.

Concept introduction:

Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation,

$\text{Molality}\text{(mol}{\text{kg}}^{\text{-1}}\text{)}\text{=}\frac{\text{Mass}\text{of}\text{solute}\text{(in}\text{g)}}{\text{Mass}\text{of}\text{solvent}\text{(in}\text{kg)}}$

(b)

Interpretation Introduction

Interpretation:

The molality of given $\text{ KBr}$ solution has to be calculated.

Concept introduction:

Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation,

$\text{Molality}\text{(mol}{\text{kg}}^{\text{-1}}\text{)}\text{=}\frac{\text{Mass}\text{of}\text{solute}\text{(in}\text{g)}}{\text{Mass}\text{of}\text{solvent}\text{(in}\text{kg)}}$

(c)

Interpretation Introduction

Interpretation:

The molality of given Aspirin solution has to be calculated.

Concept introduction:

Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation,

$\text{Molality}\text{(mol}{\text{kg}}^{\text{-1}}\text{)}\text{=}\frac{\text{Mass}\text{of}\text{solute}\text{(in}\text{g)}}{\text{Mass}\text{of}\text{solvent}\text{(in}\text{kg)}}$
