Question

A sample of compressed methane has a volume of 648 mL at a pressure of 503 kPa. To what pressure would the methane have to be compressed in order to have a volume of 216 mL?

Answer 1

P is inversely proportional to V

Therefore, P1V1 = P2V2

503 × 648 = 216 × P2

P2 = 503 × 3

P2 = 1509 kPa

Hope it helps ;-)
