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.
The rate of effusion of NH3 gas through a porous barrier is observed to be 3.47 x 10 mol/h. Under the same conditions, the rate of effusion of O2 gas would be mol/h.
7. A gaseous hydrocarbon is found to effuse through a porous barrier in 1.50 min. Under the same conditions of temperature and pressure, it takes an equal volume of bromine (Br2) vapor 4.73 min to effuse through the same barrier. Calculate the molar mass of the hydrocarbon. ANSWER: 16.1 g/mol
Rate of Effusion Problems
The average molecular speed in a sample of He gas at a certain temperature is 1.37x10 m/s. The average molecular speed in a sample of Kr gas is m/s at the same temperature. The rate of effusion of CH4 gas through a porous barrier is observed to be 3.73 x 10-4 mol/h. Under the same conditions, the rate of effusion of N2 gas would be mol/h.
a sample of CO2 gas is observed to effuse through a pourous barrier in 4.05 minutes. Under the same conditions, the same number of moles if an unknown gas requires 4.28 minutes to effuse through the same barrier. The molar mass of the unkown gas is what?
The average molecular speed in a sample of He gas at a certain temperature is 1.37x10 m/s. m/s at the same temperature. The average molecular speed in a sample of Kr gas is The rate of effusion of CH4 gas through a porous barrier is observed to be 3.73 x 10 mol/h Under the same conditions, the rate of effusion of N2 gas would be mol/h
