Molar Heat Capacities: a Compression, at a Constant Pressure of 190

Molar heat capacities: A compression, at a constant pressure of 190 kPa, is performed on 5.0 moles of an ideal monatomic gas. The compression reduces the volume of the gas from to The ideal gas constant is R = 8.314 J/mol ∙ K. The work done by the gas is closest to

A) -13 kJ.
B) 13 kJ.
C) -33 kJ.
D) 33 kJ.
E) 0.00 kJ.
