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?
Question 1 4 pts The molar mass of an unknown gas was measured by an effusion experiment. It was found that it took 64.1 seconds for the gas to effuse, where as nitrogen gas required 48.0 seconds. The molar mass of the gas is g/mol.

Post Lab #1 A student was assigned the task of determining the molar mass of an unknown gas. The student measured the mass of a sealed 843 mL rigid flask that contained dry air. The student then flushed the flask with the unknown gas, resealed it, and measured the mass again. Both the air and the unknown gas were at 23.0°C and 750. torr. The data for the experiment are shown in the table below. Volume of sealed flask 843...
Calculate the molar mass of a gas if 2.50 g occupies 0.865 dm3 at 87.3 kPa and 31 ∘C
A student devised an experiment to determine the molar mass of an unknown gas X. Firstly, he filled a glass gas syringe (accurate to ± 0.5 cm3 ) with 100 cm3 of air then placed a rubber seal over the nozzle and weighed the syringe. He then emptied the gas syringe, refilled it with 100 cm3 of the unknown gas X, replaced the rubber seal and reweighed the syringe. Finally, he measured the temperature of the room. He obtained the...
A sample of N2 gas is contaminated with a gas (A) of unknown molar mass. The partial pressure of each gas is known to be 200. torr at 25°C. The gases are allowed to effuse through a pinhole, and it is found that gas A escapes at 2 times the rate of N2. The molar mass of gas A is: 56 g/mol 14.01 g/mol 7.00 g/mol 112 g/mol none of these
If the gas has a molar mass of 86 g/mol, what is the density of a gas (in g/L) at 25.0°C and 124.1 kPa?
