Alberto Schwartz · Answer 1

To solve this problem, we will use Boyle's law which states that:

At constant temperature, P1V1 = P2V2 where:

P1 is the initial pressure = 760 torr

V1 is the initial volume = 5 liters

P2 is the final pressure that we want to calculate

V2 is the final volume = 3 liters

Substitute in the above equation to get P2 as follows:

(760) (5) = P2 (3)

P2 = (760*5) / (3) = 1266.667 torr
