Homework Statement



A cylinder contains 270 L of hydrogen gas (H2 at 0.0 C) and a pressure of 10 atm. How much energy is required to raise the temperature of this gas to 31°C? (answer needs to be kJ)

Homework Equations


PV =nRT
and
Q= MCT



The Attempt at a Solution


PV = nRT==> M= .12061 kg
Q = MC T
(.12061)(.014304) (31) ====> also tried using kelvins instead of celsius for temp...neither has worked

The MW of H2= 2 gms so your mass is off by a factor of 2 as well.
