Chapter 4, Problem 4.7P

Interpretation Introduction

Interpretation:

The volume required to dilute $100.0\text{ml}$ of a $5.00\text{M}{\text{CaCl}}_{\text{2}}$ solution to obtain a $0.750\text{M}{\text{CaCl}}_{\text{2}}$ solution is to be calculated.

Concept introduction: The dilution equation is,

$M_1{V}_1=M_2{V}_2$

This equation works as it gives the number of moles of solute that is equal in both the solutions when molarity is multiplied by the volume.

To determine: The volume required to dilute $100.0\text{ml}$ of a $5.00\text{M}{\text{CaCl}}_{\text{2}}$ solution to obtain a $0.750\text{M}{\text{CaCl}}_{\text{2}}$ solution.
