Liquid oxygen can be produced for use as a rocket fuel by cooling dry air to -183°C, where the o, condenses. How many liters of dry air at 25°C and 750 torr would need to be processed to produce 150 L of liquid O, at -183°C? The mole fraction of oxygen in dry air is 0.21, and the density of liquid oxygen is 1.14 g/mL. A mixture of helium and neon gases has a density of 0.225 g/L at 31.0°C...
