Compute the molar mass of the unknown gas

Reference no: EM13230750

A gas of unknown molar mass was allowed to effuse through a small opening under constant pressure conditions. It required 731 s for 1.00 L of this gas to effuse. Under identical experimental conditions it required 696 s for 1.00 L of argon 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 40.9 g/mol.

b) The molar mass is 36.2 g/mol.

c) The molar mass is 44.1 g/mol.

d) The molar mass is 39.0 g/mol.

e) The molar mass is 42.0 g/mol.
