Question

If 'M' is the molecular weight of a gas, what volume in $l$ at STP would be occupied by M/4 g of that gas?

• A. 11.2
• B. 2.24
• C. 5.6
• D. 22.4

Answer 1

The correct option is C 5.6

If 'M' is the molecular weight of a gas, then $M/4$ g corresponds to $1/4$ moles.

At STP, $1$ mole of gas occupies a volume of $22.4$ L.

At STP, $\frac{1}{4}$ mole of gas occupies a volume of $\frac{22.4}{4}=5.6$ L.

Hence, option C is correct.
