Chapter 14, Problem 75AE

Interpretation Introduction

Interpretation:

Molarity of phosphoric acid solution that has $85\text{ \%}$ by mass ${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}$ and density of $1.7\text{ g/mL}$ has to be determined.

Concept Introduction:

Molarity is amount of solute per $1\text{ L}$ of solution. Expression to calculate molarity is as follows:

  $\text{Molarity of solution}=\frac{\text{Moles of solute}}{\text{Volume }\left(\text{L}\right)\text{ of solution}}$
