Question

A cylinder with a moveable piston contains 0.594 mol of gas and has a volume of 240 mL.

What will its volume be if an additional 0.174 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)

Answer 1

Avagadro law states that

equal volumes of all gases, at the constant temperature and pressure, have the same number of moles

van for same gas at two different conditions V = V₂ ; V₂ = V , M 2 . ni nz Vi=240mL V₂ = ? n = 0.594 mole n₂ = 0.594 +0.174 R = 0.768 more V=240X0.768 0.594 [/₂ = 310.30 mL
