Chapter 15, Problem 9ALQ

Interpretation Introduction

Interpretation:

The reason as to why ${\text{M}}_1{\text{V}}_1={\text{M}}_2{\text{V}}_2$ works when solving dilution problems is to be stated.

Concept Introduction:

The atomic mass of an element is defined as the sum of the number of protons and the number of neutrons. Molar mass of an element is determined from the atomic mass of an element.

The moles of any element is calculated by the formula,

$\text{Moles}=\frac{\text{Mass}\left(\text{g}\right)}{\text{Molar}\text{mass}}$

Molarity is used to find out the concentration of solution.

The formula to calculate molarity is,

$\text{Molarity}=\frac{\text{Number}\text{of}\text{moles}\text{of}\text{solute}}{\text{Liters}\text{of}\text{solution}}$.
