A quantity of 0.020 mole of a gas initially at 0.050 L and 20 degrees Celsius undergoes a constanttemperature expansion until its volume is 0.59 L. Calculate the work done (in joules) by the the gas if it expands (b) pressure of 0.20 atm.
(C) If gas in (b) is allowed to expand unchecked until its pressure is equal to the external pressure, what would its final volume be before it stopped expanding, and what would be the work done?
For part b, I got the work done to be 9.117 J, but I have no idea how to do part C.
