Chapter 7, Problem 7.50E

Interpretation Introduction

(a)

Interpretation:

The molarity of the solution prepared by diluting $\text{50}\text{.0}\text{mL}$ of $0.195\text{M}\text{KBr}$ solution to each of the given final volumes isto be calculated.

Concept introduction:

A solution is prepared by mixing proper amount of solute and solvent. The expression that is used to calculate the amount of dilution of solutions is shown below.

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

Where,

• $M_1$ is the initial molarity.

• $M_2$ is the final molarity.

• $V_1$ is the initial volume.

• $V_2$ is the final volume.
