Question

Identify the gases which occupy the volume equal to the volume occupied by 1g of hydrogen gas at STP?

• A. $32g$ of oxygen
• B. $14g$ of nitrogen
• C. $35.5g$ of chlorine
• D. $4g$ of helium

Answer 1

Answer: (B), (C)

$14g$ of nitrogen
$35.5g$ of chlorine

At STP, volume of 2g of $H_2$ = $22.4l$
$\therefore$ volume of 1g of $H_2$ = $11.2l$
A) At STP, volume of 32g of oxygen = $22.4l$
B) At STP , volume of 28g of nitrogen = $22.4l$
$\therefore$ volume of 14g of nitrogen = 11.2l
C) At STP, volume of 71g of chlorine = $22.4l$
$\therefore$ volume of 35.5g of chlorine = $11.2l$
D) At STP volume of 4g of helium = $22.4l$
Therefore $\left(B\right)$ and $\left(C\right)$ has same volume as 1g of hydrogen at STP.
