what is the final and initial temperature?
You have 1.6 moles of a fictitious ideal gas whose molar specific heat values are Cv = 12.93 J/(mol·K) and Cp = 21.24 J/(mol·K). The gas expands from an initial volume of 0.0205 m3 to a final volume of 0.0370 m3 at a constant pressure of 1.89 atm.

T = PV / nR = (1.89 atm) x (20.5 L) / ((1.6 mol) x (0.08205746 L atm/K mol)) = 295 K initially
(295 K) x (0.0370 m^3 / 0.0205 m^3) = 532 K finally
