Can you help me solve this chemistry problem?

Question

A sample of gas occupies 9.25L at a pressure of 832 Torr. Maintaining a constant temperature (as well as a constant amount of gas), determine the pressure of the gas if the volume is expanded to 11.75L.

Answer 1

You would use boyle's law

P1V1 = P2V2

(9.25 Liters)(832 torr)=(11.75 Liters)(P2)

P2 = 655 torr

Answer 2

Boyle's law
P1 x V1 = P2 x V2

(9.25 L)(832 torr) = (11.75 L)(P2)
