Question

Calculate number of moles of ${N a}_{2} {S O}_{4}$ produced from 1 mole of $N a O H$
$2 N a O H + H_{2} {S O}_{4} \to {N a}_{2} {S O}_{4} + 2 H_{2} O$

Open in App

Solution

$2 N a O H + H_{2} S O_{4} ⟶ {N a}_{2} S O_{4} + 2 H_{2} O$
From the above reaction,
1 mole of ${N a}_{2} S O_{4}$ is produced by 2 moles of $N a O H$
$∴$ No. of moles of ${N a}_{2} S O_{4}$ produced by 1 mole of $N a O H = \frac{1}{2} moles$
Hence, half mole of ${N a}_{2} S O_{4}$ nis produced by 1 mole of $N a O H$ .
