So, STP (standard temperature and pressure)is 273K and 1 atm.

Since no mention is made of the temperature changing, we can assume the temperature is constant, and we can solve the problem with the info provided by using Boyle's law:

P1V1 = P2V2

P1 = initial pressure = 1 atm

V1 = initial volume = 461 mls

P2 = final pressure = 0.76 atm

V2 = final volume = ?

Solving for V2 we have...

V2 = P1V1/P2 = (1 atm)(461 mls) / 0.76 atm)

V2 = 607 mls
