Question

Volume occupied by 10 g of hydrogen at STP in litres is

• A. 224
• B. 112
• C. 56
• D. 22.4

Hint:

At STP, 1 mole of gas occupies 22.4 L. Use this value to calculate the volume of gases.

Answer 1

The Correct Option is D

At STP, 1 mole of any ideal gas occupies 22.4 litres. The molar mass of hydrogen (H\(_2\)) is 2 g. Thus, 10 g of hydrogen corresponds to $\frac{10}{2} = 5$ moles of hydrogen. The volume occupied is then $5 \times 22.4 = 112$ litres.
