Pure O_(2) diffuses through an aperture in 224 second, whereas mixture of O_(2) and another gas containing 80% O_(2) diffuses from the same in 234 second. The molecular mass of gas will be:

One mole of N_(2) gas at 0.8 atm takes 38 sec to diffuse through a pin hole whereas 1 mole of an unknown compound of xenon with fluorine at 1.6 atm takes 57 sec to diffuse through the same hole. Calculate the molecular formula of the compound

In a mixture of O_(2) and an unknown gas, the percentage of the unknown gas is 20% by mass. At a given temperature and pressure, time required to effuse V mL of the gas mixture through an aperrture is 234.1 s. under the same conditions, time required to effuse the same volume of pure O_(2) gas is 223.1 s. what is the molar mass of unknown gas?

It takes 192 sec for an unknown gas to diffuse through a porous wall and 84 sec for N_(2) gas to efffuse at the same temperature and pressure. What is the molar mass of the unknown gas?

At 27^(@) C , hydrogen is leaked through a tiny hole into a vessel for 20 min . Another unknown gas at the same T and P as that of H_(2) , is leaked through the same hole for 20 min. After the effusion of the gases the mixture exerts a pressure of 6 atm. The hydrogen content of the mixture is 0.7 mole. If the volume of the container is 3 litre, what is molecular weight of unknown gas ? ("Use" : R = 0.821 "L atm K"^(-1) "mole"^(-1))
