Chapter 12, Problem 141CP

Interpretation Introduction

Interpretation: The molality of HCl solution should be calculated.

Concept introduction: Molarity is defined as the amount of solution present in 1 L of the solution. It is mathematically represented as follows:

  $M=\frac{n\left(\text{solute}\right)}{V\left(\text{solution,L}\right)}$

Here, n is number of moles and V is volume of solution in L.

The number of moles is related to mass and molar mass as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.
