If an aerosol can contained 350mL of CFC gas at a pressure of 5.1 atm, what volume would this gas occupy at 1.0atm?

For this case we have the following relationship:

P1V1 = P2V2

Clearing volume 2 we have:

V2 = (P1 / P2) * (V1)

Substituting values we have:

V2 = (5.1 / 1.0) * (350)

V2 = 1785 mL

Answer:

this gas would occupy 1785 mL at 1.0atm
