A sample of unknown gas A (g) escapes through a tiny hole into a vacuum chamber in 187.5 s. The same concentration of unknown gas X2 (g) escapes through the hole into the evacuated vacuum chamber in 101.3 s under identical conditions. You are given that X2 (g) is a homonuclear diatomic gas, and that a 13.129 g sample of A (g) in a 1.500 L flask at 25.00 oC has a measured pressure of 1.631 atm. Identify both A (g) and X2 (g). Justify your answer with calculations. (4 significant figures)
