HELP!!! I have a cylinder sitting in my lab that contains 0.500 L of 25.85 C gas, and it's pressure is 14.7 psi. If I push the cylinder and increase the pressure to 22.6 psi and the temperature to 59.85 C, what will be the new volume of the gas in L?

P1xV1 = nRT1

P2xV2 = nRT2

Since the number of moles of gas don't change and the gas constant is, well, constant, take the ratios of both sides of the equations and solve for V2. Convert from C to K, but you can leave the pressures as psi.

(P1xV1)/(P2xV2) = (T1/T2)
