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.) 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
