Question

$0.32$ g of a metal gave on treatment with an acid $112$ mL of hydrogen at NTP. Calculate the equivalent mass of the metal.

• A. $58$
• B. $32$
• C. $64$
• D. $24$

Answer 1

The correct option is B $32$

Eq. wt of metal $=\frac{\text{wt of metal}\times 11200}{\text{V of}{H}_2\text{in ml displaced at STP}}=\frac{0.32\times 11200}{112}=32$
