Thermodynamics: Two Step Process

Question: Consider the following two-step process. Heat is allowed to flow out of an ideal gas at constant volume so that its pressure drops from P1 = 2.19 atm to P2 = 1.58 atm. Then the gas expands at constant pressure, from a volume of V1 = 6.38 L to V2 = 10.5 L, where the temperature reaches its original value. See the attached figure.

Calculate the total work done by the gas in the process and calculate the total heat flow into or out of the gas.
