The rate of diffusion of $SO_3$,$CO_2$,$PCl_3$ and $SO_2$ gases are in the following order:

$5$ moles of a gas is allowed to pass through a series of changes as shown in the graph,in a cyclic process. The processes $C \rightarrow A$,$B \rightarrow C$ and $A \rightarrow B$ respectively are

$A$ mixture of one mole each of $H_2$,$He$ and $O_2$ are enclosed in a cylinder of volume $V$ at temperature $T$. If the partial pressure of $H_2$ is $2 \ atm$,the total pressure of the gases in the cylinder is $....... \ atm$

If equal masses of $CO$ and $N_2$ are filled in a container,the relationship between their partial pressures will be ................

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:

It takes $38 \, s$ for $1 \, mol$ of $N_2$ gas to effuse through a pinhole at a pressure of $0.8 \, atm$. It takes $57 \, s$ for $1 \, mol$ of an unknown gas $X$ to effuse through the same pinhole at a pressure of $1.6 \, atm$. Calculate the molar mass of $X$.
