The rate of diffusion of hydrogen 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 $X$.

$80 \ mL$ of $O_2$ takes $2 \ minute$ to pass through the hole. What volume of $SO_2$ will pass through the hole in $3 \ minute$?

Which physical property decreases with an increase in intermolecular forces?

At $T \ K$,hydrogen and oxygen gases are mixed in the ratio of $1:2$ by mass in a closed vessel of volume '$V$' litres. If the total pressure of the gaseous mixture is '$p$' atm,the partial pressure of oxygen (in atm) is

Two grams of hydrogen diffuse from a container in $10 \ min$. How many grams of oxygen would diffuse through the same container in the same time under similar conditions?
