Chapter 4, Problem 32E

Interpretation Introduction

Interpretation:

The mass of ${\text{CaCl}}_{\text{2}}$ needed to make $7.2\text{L}$ of a $0.350\text{M}{\text{CaCl}}_2$ solution is to be calculated.

Concept introduction:

The mass of a compound is calculated by the formula,

$\text{Mass}=\text{Moles}\times \text{Molar}\text{mass}$

The concentration of a solution is defined as the number of moles of solute dissolved in a liter of solution. Concentration of a solution is expressed in moles per unit volume of a substance.

To determine:

The mass of ${\text{CaCl}}_{\text{2}}$ needed to make $7.2\text{L}$ of a $0.350\text{M}{\text{CaCl}}_2$ solution.
