1 ) Balance the chemical equation

$2KClO_3\rightarrow2KCl+3O_2$

2) Convert grams of potassium chlorate into moles of potassium chlorate.

The molar mass of KClO3 is 122.55 g/mol.

$\text{mol KClO}_3=25.0gKClO_3\cdot(1molKClO_3)/(122.55gKClO_3)=0.2040molKClO_3$

3) How many moles of KCl are produced from 0.2040 mol KClO3.

The molar ratio between KCl and KClO3

2 mol KCl:2 mol KClO3

$\text{mol KCl}_{}=0.2040molKClO_3\cdot\frac{2molKCl_{}}{2molKClO_3}=0.2040molKCl_{}$

4) Convert moles of KCl into grams of KCl

The molar mass of KCl is 74.55 g/mol

$gKCl_{}=0.2040molKCl\cdot\frac{74.55gKCl_{}}{1molKCl_{}}=15.20gKCl_{}$

15.20 g KCl will be produced.
