If $P_1$ is the partial pressure of a gas and $x_1$ is its mole fraction in a mixture,then the correct relation between $P_1$ and $x_1$ is:

At $298 \, K$,equal masses of $SO_2, CH_4$,and $O_2$ are placed in an empty container. The total pressure of the mixture is $2.1 \, atm$. The partial pressure of $CH_4$ in the mixture is ........... $atm$.

Deep sea divers use a mixture of which gases for respiration?

In a container,the mole ratio of two gases $A$ and $B$ is $2 : 5$. The total pressure of the container is $3.5 \times 10^5 \ Pa$. If all molecules of $A$ are removed from the container,what will be the pressure exerted by the molecules of $B$?

The ratio of the partial pressure of a gaseous component to the total vapor pressure of the mixture is equal to .......
