What is the initial pressure of a gas having an initial temperature of 90.5 K, an initial volume of 40.3 L, a final pressure of 0.83 atm, a final temperature of 0.54 K and a final volume of 2.7 L?
EDIT: This pressure is moderate, but the temperature is quite low. So the gas is probably not very ideal. Nevertheless, the idea is probably to assume ideality anyway.

Explanation:
#PV = nRT#
#(PV)/T = nR#
#therefore (P_1V_1)/T_1 = (P_2V_2)/T_2# , the combined gas law.
#(P_1*"40.3 L")/("90.5 K")=("0.83 atm"*"2.7 L")/("0.54 K")#
#P_1 approx 9.3atm#
