Chapter 13, Problem 41E

Interpretation Introduction

Interpretation:

The concentration of each solution in mass percent is to be calculated.

Concept introduction:

The number of grams of solute present in $100g$ of solution is called mass percent of the solution.

Mass percent of a solution is obtained by dividing the mass of solute by the mass of solution (i.e. mass of solute and mass of solvent) and multiplying by $100\%$.

Mathematically, the mass percent of a substance is written as:

$\text{Mass percent}=\frac{\text{mass solute}}{\text{mass solute}+\text{mass solvent}}\times 100\%$
