A gas of unknown molar mass was allowed to effuse through a small opening under constant pressure conditions. It required 184 s for 1.00 L of this gas to effuse. Under identical experimental conditions it required 506 s for 1.00 L of chlorotrifluoromethane (CClF3) gas to effuse. Calculate the molar mass of the unknown gas . (Remember that the faster the rate of effusion, the shorter the time required for effusion; that is, rate and time are inversely proportional.)

a) The molar mass is 287.3 g/mol.

b) The molar mass is 790.0 g/mol.

c) The molar mass is 63.0 g/mol.

d) The molar mass is 173.2 g/mol.

e) The molar mass is 13.8 g/mol.
