A Molecule of H2 Can travel an average distance of 92 nm before it collides with another H2 molecule in a 2.09 L container that has 0.87 mol of H2 (g) with a total pressure of 0.98 atm. What is the temperature of the container in K? Assume the diameter of H2 to be 1.09 angstrom.

Perhaps I've missed something but I don't see what all of that information about collisions and 92 nm has to do with the problem. Use PV = nRT, substitute the numbers in the problem and solve for T in kelvin.
