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))`
