Chapter 13, Problem 15QP

Interpretation Introduction

Interpretation:

The percent mass of the solute in each of givenaqueous solutions is to be calculated.

Concept introduction:

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

Percent by mass of a solution is obtained by dividing the mass of solute by the mass of solution (i.e., the mass of solute and mass of solvent), which is then multiplied by $100\%$.

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

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