Find the pressure of a gas that originally had a volume of 25 L, pressure of 67kPa at a temperature of 100 Kelvin. When the gas was heated to 200 Kelvin, it had a volume of 56L.

How many moles would be present if the gas in the above question was an ideal gas?

For the first part, use

(P1V1/T1) = (P2V2/T2)

Solve for P2 (I guess that's what the problem is asking for. It's a funny way, and confusing way, of stating a problem.

For the second part, use any set of P, V, T, and use PV = nRT and solve for n = number of moles.
