Chapter 4, Problem 38E

Interpretation Introduction

Interpretation:

The volume of $0.150\text{M}{\text{Li}}_2\text{S}$ solution required to completely react with $125\text{mL}$ of $0.\text{150}\text{M}\text{Co}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ is to be calculated.

Concept introduction: The dilution equation is,

${\text{M}}_{\text{1}}{\text{V}}_{\text{1}}={\text{M}}_{\text{2}}{\text{V}}_{\text{2}}$

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 volume of $0.150\text{M}{\text{Li}}_2\text{S}$ solution required to completely react with $125\text{mL}$ of $0.\text{150}\text{M}\text{Co}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ .
