Solution

The correct option is A $0.53 g$
Using stoichiometry,

$E q_{H_{2} S O_{4}} = E q_{N a_{2} C O_{3}}$

$2 \times 0.05 \times \frac{100}{1000} = 2 \times m o l e s_{(} N a_{2} C O_{3})$

$M o l e s o f N a_{2} C O_{3} = \frac{5}{1000}$

Therefore, weight of $N a_{2} C O_{3} = 106 \times \frac{5}{1000} g m = 0.53 g m$
