According to the ideal gas law, a 1.074 mol sample of oxygen gas in a 1.746 l container at 267.6 k should exert a pressure of 13.51 atm. what is the percent difference between the pressure calculated using the van der waals' equation and the ideal pressure? for o2 gas, a = 1.360 l2atm/mol2 and b = 3.183×10-2 l/mol.

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
