Chapter 12, Problem 41E

Interpretation Introduction

Interpretation:

The mass of $\text{NaCl}$ in a given solutions is to be calculated.

Concept Introduction:

The same solute and solvent can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solution. The amount of a solute present in a given amount of a solvent is defined as its concentration.

Mass percent is defined as the mass of a solute present in $100$ g of a solution.

Density is the ratio of the mass of a substance to its volume.

A mole is a unit of amount of a substance. It relates the number of particles to molar mass.

Density of a solution as presented as:

$\text{Density}=\frac{\text{Mass of solution}}{\text{Volume of solution}}$

As 1 L is equal to 1000 mL, hence the conversion factor will be as:

$\frac{1000\text{mL}}{1\text{L}}$

$\text{Mass percent of compound}=\frac{\text{Mass of compound}}{\text{Mass of solution}}$
