A 55.0 L, 2.20 mole sample of air, composed in this case of N2 with molar fraction of 75% and O2 with molar fraction of 25%, is separated into its components (by passing it over a liquid nitrogen trap, which condenses the oxygen). The separated N2 and O2 are then each allowed to return to the pressure and temperature of the initial air sample. R = 8.314 JK mol-1. Part A Calculate AS. Assume that N2 and O2 are ideal gases. Express your answer to three significant figures and include the appropriate units. HA ? AS = Value Units Submit Request Answer A 55.0 L, 2.20 mole sample of air, composed in this case of N2 with molar fraction of 75% and O2 with molar fraction of 25%, is separated into its components (by passing it over a liquid nitrogen trap, which condenses the oxygen).
