Q. What mass of sodium chloride would be decomposed by $9.8 g$ of sulphuric acid if $12 g$ of sodium bisulphate and $2.75 g$ of hydrogen chloride were produced in a reaction?

$14.75 g$

$3.8 g$

$4.95 g$

$2.2 g$

$x N a Cl + 9.8 g H_{2} S O_{4} ⟶ 12 g N a H S O_{4} + 2.75 g H Cl$
$x + 9.8 = 12 + 2.75$
$\Rightarrow x = 4.95 g$
