Chapter 1, Problem 1.23P

(a)

Interpretation Introduction

Interpretation:

The number of grams of $70.5wt\%$ aqueous solution of perchloric acid contained in $1.00L$ has to be calculated.

Concept Introduction:

Weight percent is one of parameters used to express concentration of a solution.  It is expressed as,

$\text{Weight percent of a solute = }\frac{\text{weight of solute}}{\text{weight of solution}}\times \text{ 100\%}$
