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

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.
The effusion rate of an unknown gas is measured and found to be 31.50 mL/min. Under identical experimental conditions, the effusion rate of O2(g) is found to be 30.50 mL/min. What is the molar mass of the unknown gas?
A gas effusion cellis loaded with O2 gas at STP it take 344 seconds 0.010% of the gas to effuse through the hole. Under the same conditions, an unknown gas takes 46 3 seconds for 0.010% of gas to offuse through the hole. Based on these data, what is the molar mass of the unknown gas in gimoll?
