Chapter 4, Problem 61E

Interpretation Introduction

Interpretation:

The molarity of the NaOH in the given reaction needs to be calculated.

Concept introduction:

The ratio of moles in which reactant reacts and products are formed in a reaction is called stoichiometric ratio.

Molarity is defined as number of moles of solute in 1 L of the solution.

$M=\frac{n}{V\left(L\right)}$

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

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

$n=\frac{m}{M}$

Here, m is mass and M is molar mass.
