  • The density of liquid oxygen is 1.141 kg/L Ref: http://en.wikipedia.org/wiki/Liquid_oxygen 1 gallon = 3.785 Liters Ref: http://www.metricamerica.com/convert%20gallons%20to%20liters.htm So one gallon of liquid oxygen weighs: (3.785 L/gal)*(1.141 kg/L)*(1000 grams/kg) = = 4,319 grams. Molecular oxygen is diatomic (formula O2) in both gas and liquid phase, so one mole of oxygen has the same mass in grams as the molecular weight of oxygen, which is twice the atomic weight. The atomic weight of oxygen is 16.00 grams/mole Mol. wt of oxygen = 2*(16) = 32 grams/mole So one gallon of liquid oxygen contains: (4,319 g) / (32 g/mole) = 135 moles.
