Answer on Inorganic Chemistry Question for Ann Vincent

Question #19903
1. A vessel with a tiny hole in its wall is filled with oxygen (O2) to a pressure of 1 atm at 25oC. In a one-minute period, 3.25g of oxygen effuse out through the hole into a vacuum. The vessel is evacuated and filled with an unknown gas at the same pressure and temperature. In this case, only 1.96g of the unknown gas effuse out in one minute. Calculate the molar mass of the unknown gas.
Expert's answer
n = m/Mw,so n(O2) = 3.25/32 = 0.1015 mol, and it isequivalent to the n of the unknown gas, if n = m/Mw =>
Mw = m/n = 1.96/0.1015 = 19.310
