Chapter 3, Problem 3.73P

(a)

Interpretation Introduction

Interpretation:Moles of ${\text{H}}_2{\text{SO}}_{\text{4}}$ present per milliliter of solution is to be calculated.

Concept introduction: Masspercent indicates concentration with respect to fraction in parts per hundred parts. For example $30\text{ \%}$ mass percent can represent $30\text{ g}$ solute in $100\text{ g}$ solution or $30\text{ mL}$ solute in $100\text{ mL}$ solution.

The formula to calculate volume from density is as follows:

  $\text{Mass}=\left(\text{Volume}\right)\left(\text{Density}\right)$
