A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.661 mol of a gaseous product. If the cylinder contained 0.220 mol of gas before the reaction and had an initial volume of 2.12 L , what was its volume after the reaction? (Assume that pressure and temperature are constant and that the initial amount of gas completely reacts.)
