Gas Laws & Ideal Gas Equation

A sample of oxygen gas and a sample of hydrogen gas both have the same mass, same volume and the same pressure. The ratio of their absolute temperature is (Molecular wt. of $\text{O}_2 \,\&\, \text{H}_2$ is 32 and 2 respectively)

Show answer and solution

Answer: (c)

$PV = \dfrac{m}{M}RT$ ; same $m$ , $P$ , $V$ $\Rightarrow T \propto M$ .
$\dfrac{T_{O_2}}{T_{H_2}} = \dfrac{32}{2} = 16$
So the answer is (c) $16 : 1$ .
