Find the mass of $K N O_{3}$ required to produce 126 kg of nitric acid. Find whether a larger or smaller mass of $N a N O_{3}$ is required for the same purpose.
$K N O_{3} + H_{2} S O_{4} \to K H S O_{4} + H N O_{3} N a N O_{3} + H_{2} S O_{4} \Rightarrow N a H S O_{4} + H N O_{3}$

Solution

Molar mass of $H N O_{3}$ = 1+14+48 = 63 g
Molar mass of $K N O_{3}$ = 101 g
63 g of $H N O_{3}$ is produced from 101 g of $K N O_{3}$
126 g of $H N O_{3}$ is produced from $\frac{101}{63} \times 126$ of $K N O_{3}$ = 202 g of $K N O_{3}$
63 g of $H N O_{3}$ is produced from 101 g of $K N O_{3}$
Molar mass of $N a N O_{3}$ = 85 g
63 g of $H N O_{3}$ is produced from 85g of $N a N O_{3}$
Thus smaller mass of $N a N O_{3}$ will be required.
