Two moles of helium gas initially at 253 K and 0.2 atm are compressed isothermally to 1.72 atm. Find the final volume of the gas. Assume that helium behaves as an ideal gas. The universal gas constant is 8.31451 J/K · mol. Answer in units of m3 .

Find the work done by the gas. Answer in units of kJ. 020

Find the thermal energy transferred. Answer in units of kJ.

I know that the work done by the gas is -9.05277, and that Q = -W, but when I put in 9.05277 for the amount of thermal energy transferred its wrong.
