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 6.71 mL of O2 had passed through the membrane, but only 3.14 mL of of the unknown gas had passed through. What is the molar mass of the unknown gas? Number g/mol
A sample of Cl2 requires 51.1s to effuse. Under the same conditions, an equal amount of an unknown gas effuses in 32.1s. What is the molecular weight of the unknown gas?
A sample of He gas is observed to effuse through a porous barrier in 8.83 minutes. Under the same conditions, the same number of moles of an unknown gas requires 30.1 minutes to effuse through the same barrier. The molar mass of the unknown gas is ___ g/mol
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.)...
A sample of CH4 gas is observed to effuse through a porous barrier in 6.35 minutes. Under the same conditions, the same number of moles of an unknown gas requires 14.8 minutes to effuse through the same barrier. The molar mass of the unknown gas is ___g/mol.
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?
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 7.83 mL of O2 had passed through the membrane, but only 3.87 mL of of the unknown gas had passed through. What is the molar mass of the unknown gas?
A sample of O2 gas is observed to effuse through a pourous barner in 5.93 minutes. Under the sa,e number of moles of an unknown gas requires 3.92 minutes to effuse through the same barrier. The molar mass the unknown gas is g/mol.
A sample of He gas is observed to effuse through a pourous barrier in 8.78 minutes. Under the same conditions, the same number of moles of an unknown gas requires 22.1 minutes to cffuse through the same barrier.

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.)
