A 10.58 mol sample of xenon gas is maintained in a 0.8497 L container at 296.8 K. What is the pressure in atm calculated using the van der Waals' equation for Xe gas under these conditions? For Xe, a = 4.194 L2atm/mol2 and b = 5.105×10-2 L/mol.

According to the ideal gas law, a 0.9613 mol sample of nitrogen gas in a 1.181 L container at 273.6 K should exert a pressure of 18.27 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For N2 gas, a = 1.390 L2atm/mol2 and b = 3.910×10-2 L/mol.

The rate of effusion of gas through a porous barrier is observed to be mol/h.

Under the same conditions, the rate of effusion of O3 gas would be _____ mol/h.

A sample of NH3 gas is observed to effuse through a pourous barrier in 9.83 minutes. Under the same conditions, the same number of moles of an unknown gas requires 14.2 minutes to effuse through the same barrier.

The molar mass of the unknown gas is ______ g/mol.

Solutions

Expert Solution

Answer 1 : 183.1 atm
