Combined Gas Law

The Combined Gas Law can be derived by multiplying Boyle's law by the laws of Charles and Gay-Lussac.

P1V1 = P2V2
P1V12 / T1 = P2V22 / T2
P12V12 / T12 = P22V22 / T22

By taking the square root of this result we get the combined gas law:
P1V1 / T1 = P2V2 / T2

Combined gas law

A sample of gas has an initial volume of 2dm3 (V1) at a temperature of 300 K(T1) and a pressure of 1atm (P1). If the gas is compressed to a volume of 0.5dm3(V2)and heated to 350 K(T2) what is the final pressure (P2)?
