Two separate bulbs contain ideal gases $A$ and $B$ at the same temperature. The molecular mass of $A$ is half that of gas $B$ and the density of gas $A$ is twice that of gas $B$ . The ratio of the pressure of $A$ to that of gas $B$ is

Answer:

Solution:

$d_{a} = 2 d_{b}$ ; $2 M_{a} = M_{b}$
$P V = n R T = \frac{m}{M} R T$ ; $P = \frac{m}{V} . \frac{R T}{M} = \frac{d R T}{M}$
$\frac{P_{a}}{P_{b}} = \frac{d_{a}}{d_{b}} \frac{M_{b}}{M_{a}} = \frac{2 d_{b}}{d_{b}} \times \frac{2 M_{a}}{M_{a}} = 4$
