## Question:

Consider the following reaction.

$$2KClO_3 (s) \rightleftharpoons 2KCl (s) + 3O_2(g) $$

How many grams of {eq}KCl {/eq} are produced from the complete reaction of 5.39 mol of {eq}KClO_3 {/eq}?

## Moles and Molar Mass:

If the mass of a substance is provided in {eq}\text{g} {/eq} and each substance contains its own molar mass that is measured in {eq}\text{g/mol} {/eq}. The mass of this substance per unit molar mass is referred to as the number of moles of the substance. The mathematical expression to compute the number of moles of a substance is:

$$\begin{align} \color{blue}{n=\frac{m}{M}} \end{align} $$

Here:

- {eq}m {/eq} is the given mass of the substance.

- {eq}M {/eq} is the molar mass of the substance.
