A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.641 mol of a gaseous product. If the cylinder contained 0.240 mol of gas before the reaction and had an initial volume of 2.19 L, what was its volume after the reaction? (Assume that pressure and temperature are constant and that the initial amount of gas completely reacts.)

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
