A chemical reaction occuring in a cylinder equipped with a movable piston produc

Question

A chemical reaction occuring in a cylinder equipped with a movable piston produces 0.621 mol of a gaseous product. If the cylinder contained 0.120 mol of gas before the reaction and had an initial volume of 2.18 L, what was it's volume after the reaction? (Assume constant pressure and temperature and that the initial amount of gas completely reacts.)

Explanation / Answer

PV1=n1Rt

PV2=n2Rt

Use this equation

V1/V2 =n1/n2

2.18/v2=.120/2.18

v2=25.25
