At `27^@C`, hydrogen is leaked through a tiny hole into a A+ 270 vessel for 20 minutes. Another unknown gas at the same T & P as that of `H_2` is leaked through the same hole for 20 min. After the effusion of gases the mixture exerts a pressure of 6 atm. The `H_2` content of the mixture is 0.7 moles. If the volume of the container is 3 liter, what is the molecular mass of the unknown gas?
