10 d m^3 of N_2 gas and 10 d m^3 of gas X at the same temperature… - Vidyadip

MCQ

$10$ $d{m^3}$of ${N_2}$ gas and $10$ $d{m^3}$ of gas $X$ at the same temperature contain the same number of molecules. The gas $X$ is

✓
$CO$
B
$C{O_2}$
C
${H_2}$
D
$NO$

✓

Answer

Correct option: A.

$CO$

a
(a) If same volume is occupied by the gas, the no. of molecules are same, so no. of moles are same.

$1$ mole of ${N_2}$ gas $ = 2 \times 14 = 28\,gm$

$1$ mole of $CO$ gas $ = 12 + 16 = 28\,gm$
