Two vessels $A$ and $B$ are of the same size and are at same temperature. A contains 1 g of hydrogen and $B$ contains 1 g of oxygen. $P_{A}$ and $P_{B}$ are the pressures of the gases in $A$ and $B$ respectively, then $\frac{P _{A}}{P _{B}}$ is:

Options:

Answer:

Solution:

$n_{A} = \frac{1}{2} mol, n_{B} = \frac{1}{32} mol$ By ideal gas equation, $P V = n RT \Rightarrow P \propto n$ $∴ \frac{P _{A}}{P _{B}} = \frac{n _{A}}{n _{B}} = \frac{32}{2} = 16$
