Answer to Question #304966 in General Chemistry for Chris

Question

Freon in air conditioning unit has a volume of 0.30L. It is allowed to function in a room, where the pressure is about 628 mm of Hg, assuming that the temperature is in a constant state. Find the final pressure of Freon when its volume is increased to 0.95L.

Answer 1

Boyle's law

P₁V₁ = P₂V₂

V₁ = 0.30L, V₂ =0.95L

P₁ = 628 mm of Hg

P₂ = P₁V₁/V₂ = 628 * 0.3/0.95 = 198 mm of Hg

Answer: P₂ = 198 mm of Hg
