Chapter 9, Problem 9.53AP

Interpretation Introduction

Interpretation:

Concentration in moles per liter when concentration of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is $\text{3\%(m/v)}$ has to be identified.

Concept introduction:

• Mass/volume percentage, $\left(\text{m/v}\right)\text{\%,}$ is often used for solutions of solids in liquids given by

$\text{(m/v)\%}\text{=}\frac{\text{mass}\text{of}\text{solute}}{\text{volume}\text{of}\text{solution}}\text{×}\text{100}$

• Number of moles can be calculated by using,

$\text{Number}\text{of}\text{moles=}\frac{\text{Mass}\text{of}\text{solute}}{\text{MW}}$
