The pressure under which liquid and vapour can coexist at equilibrium is called the

The total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of the individual gases under the same conditions. This is known as:

The densities of two gases are in the ratio of $1 : 16$. The ratio of their rates of diffusion is

The total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. This is known as which law?

At $T \ K$,a gaseous mixture of $H_2$ and $O_2$ containing $20 \%$ (weight/weight) of $H_2$ exerts a total pressure of $2 \ bar$. What is the partial pressure of $O_2$ (in bar)?

When $CH_4$ gas is collected over water,the total pressure is $735 \ torr$ and the temperature is $292 \ ^\circ C$. If the vapor pressure of water at $292 \ ^\circ C$ is $30 \ torr$,then the pressure exerted by the dry methane gas will be .......... $torr$.
