The rate of effusion of an unknown gas was measured and found to be 15.5 mL/min. Under identical conditions, the rate of effusion of pure oxygen (O2) gas is 18.2 mL/min. Based on this information, the identity of the unknown gas could be:
a) N2CH2OF2
b) CO2N2O
c) CO
d) C2H6
e) None of these

The rate of effusion of a particular gas was measured to be 28.6 mL/min. Under the same conditions, the rate of effusion of pure methane (CH4) gas is 48.4 mL/min. What is the molar mass of the unknown gas? g/mol
The molar mass of an unknown gas was measured by an effusion experiment. It was found that the unknown gas effused at a rate of 2.7 x 10^-6 mol/hr, whereas the nitrogen gas effused at a rate of 3.3 x 10^-6 mol/hr. What is the molar mass of the gas?
A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 67 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 31 s for 1.0 L of O2 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 of 1.0 L; that is, rate and time are inversely proportional.)
The rate of diffusion of a particular gas was measured and found to be 50.5 mm/min. Under the same conditions, the rate of diffusion of SF was 18.7 mm/min. What is the molar mass of the unknown gas? What gas might this be? One group of students in an introductory chemistry course is arguing that the pressures of a con- tainer of hydrogen gas and a container of sulfur dioxide gas, under the following conditions, cannot be equal. Both containers...
A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 52 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 27 s for 1.0 L of O2 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 of 1.0 L; that is, rate and time are inversely proportional.)...
The density of oxygen gas at a given temperature and pressure is 1.30 gL. The volume of 21.0 ml of O2 is effused from a device for 1,000 s. When the same device is used under the same conditions, the effusion rate of an unknown gas is 15.0 mL / s. What is the density of the unknown gas? Answer:2.55g/L
under identical conditions separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simultaneously. after a certain amount of time it was found that 5.39 mL of O2 had passed through the membrane but only 3.33 mL of the unknown gas had passed through, what is the molar mass of the unknown gas?
