An effusion apparatus is filled with helium at 25 C to a pressure of 726 mm Hg. It takes 2 hours 12 minutes and 6 seconds for the pressure in the apparatus to fall to 323 mm Hg. The same apparatus is them filled with an unknown gas at 32.3 C to a pressure of 645 mm Hg. It takes 5 hours 34 minutes and 25 seconds for the pressure to fall to 207 mm Hg. Calculate the molar mass of the unknown gas.
