Chapter 3, Problem 3.72P

(a)

Interpretation Introduction

Interpretation: Mass of ${\text{HNO}}_{\text{3}}$ present per liter of nitric acid solution is to be calculated.

Concept introduction:Mass percent 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:

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

(b)

Interpretation Introduction

Interpretation: Molarity of ${\text{HNO}}_{\text{3}}$ solution is to be calculated.

Concept introduction: The formula to calculate the molarity of solution is defined as follows:

  $M=\frac{n}{V\left(L\right)}$

Here, n is number of moles and V is volume in L.
