The rate of diffusion of a gas (molar mass = $128$) compared to oxygen is:

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:

$A$ $10 \ L$ vessel contains $1 \ mole$ of an ideal gas with pressure of $P \ atm$ and temperature of $T \ K$. The vessel is divided into two equal parts. The pressure (in $atm$) and temperature (in $K$) in each part is respectively:

Write the order of kinetic energy for solid,liquid,and gas.

$A$ sample of $N_2$ gas at $0.8 \, atm$ pressure takes $38 \, s$ to effuse through a pinhole. $A$ sample of $1 \, mol$ of an unknown gas '$X$' at $1.6 \, atm$ pressure takes $57 \, s$ to effuse through the same pinhole. The molar mass of gas '$X$' in $g/mol$ is .............
