A 9.96 mol sample of methane gas is maintained in a 0.836 L container at 296 K. What is the pressure in atm calculated using the van der Waals' equation for CH4 gas under these conditions? For CH4, a = 2.25 L2atm/mol2 and b = 4.28E2 L/mol.

I'm not going to work the problem for you since it's just substitution of the numbers into the van der Waals equation. However, if you will show your work I shall be happy to check it for you. If you get stuck in the middle somewhere be sure and explain what it is you don't understand.
