Question

density of a gas at 300k and 210 torr is 0.434 gl-1.. what is molar mass

Answer 1

density (d) = MP / RT  where M is molar mass, P is pressure, R is universal gas constant, T is temperature  we're finding M, so:  M = pRT / P  Given: d = 0.434  P = 210 torr  T = 300  R for torr = 62.363   M = (0.434 * 300 * 62.363) / 210  M = 38.67   Molar mass = 38.67 g/mole
