Question

A chemical reaction occuring in a cylinder equipped with a moveable piston produces 0.53 mol of a gaseous product. If the cylinder contained 0.11 mol of gas before the reaction and had an initial volume of 1.5 L, what was its volume in L after the reaction? Report answer to 2 sig figs.

Answer 1

Answer:

Initially, the cylinder had n₁ = 0.120 mol of gas in an initial volume V₁ = 2.18 L. At the end, it had n₂ = 0.621 mol in an unknown volume V₂. According to the Avogadro's law, in the same conditions of pressure and temperature, the volume is directly proportional to the number of moles.

Answer 2

Answer:

7.2 L is the right answer
