At 27^@C , hydrogen leaks through a tiny hole in a vessel for 20 minutes. Anotherunknown gas at the same temperature and pressure as that of H_2leaks through the same hole for 20 minutes. 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 litres, what is the molecular weight of the unknown gas?

1.	At 27^@C , hydrogen leaks through a tiny hole in a vessel for 20 minutes. Anotherunknown gas at the same temperature and pressure as that of H_2leaks through the same hole for 20 minutes. 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 litres, what is the molecular weight of the unknown gas?
Answer» SOLUTION :`(r_X)/(r_(H_2)) = SQRT(2/M) = (n_X)/(n_(H_2)) , pV = (n_X + n_(H_2) ) RT` 1032
