The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the

pressure when its volume is changed to 2.00 L?

Use PV = P2V2.

4.44 atm

Explanation:

Plug the information given into the formula and you get

(1.00 atm) (0.450 L) = P2 (2.00 L)

Use simple algebra to divide both sides by 2.00 L to get the unknown P2 which is 4.44 atm

(Be sure to convert the volumes to L)
