Acylinder of hydrogen has a volume of 0.1m'. its pressure is found to be 20 atm at 20°c. what mass of hydrogen does it contain? if it was filled with oxygen instead to the same pressure, how much oxygen would it contain? (molar mass of h, = 2 kg/kmol, of o2 = 32 kg/kmol, 1 atm = 105 pa, r = 8.3143 kj/kmol-k).
