A cylinder contains 260 L of hydrogen gas (H2) at 0.0° C and a pressure of 10.0 atm. How much energy is required to raise the temperature of this gas to 28.0° C? give answer in kJ.
C=Q/(delta)T and/or PV=nRT
The Attempt at a Solution
using the first equation I got an answer of 63.5 which is incorrect. I am not sure how to place the given values into the second equation because I don't know what R stands for.
the attempt with the second equation: (10.0 x 101.3)(260)=nR(28)
Thanks in advance.
