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
8. Neon gas is found to effuse through a hole. Careful measurement indicates that 1.42 x 10 mol effused in 5.8 minutes. How long (in min) would it take for the same amount of xenon gas to effuse through the same hole under the same conditions? A: 14.8
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?
8. Neon gas is found to effuse through a hole. Careful measurement indicates that 1.42 x 10 mol effused in 5.8 minutes. How long (in min) would it take for the same amount of xenon gas to effuse through the same hole under the same conditions? A: 14.8 RKSHEET 9 9. A 2.00 L bottle contains the following gases: 0.0150 mol He, 0.100 mol Ny, and 0.00250 mol Xe. If the temperature of the gas mixture is 22.4 °C, what...
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 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 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.
