A gas at constant temperature occupies a volume of 3.49 L and exerts a pressure of 830. torr. What volume (in L) will the gas occupy at a pressure of 588 torr?

Question

A gas at constant temperature occupies a volume of 3.49 L and exerts a pressure of 830. torr. What volume (in L) will the gas occupy at a pressure of 588 torr? 

Answer 1

Constant temperature requires Boyles Law:

P1V1 = P2V2

P1 = 830 torr

V1 = 3.49 L

P2 = 588 torr

V2 = ?

(830 torr)(3.49 L) = (588 torr)(V2)

V2 = (830)(3.49)/588

V2 = 4.93 L
