Formula and Answer Check
Find the volume of a gas at -30 C and 0.75 atm if it occupies a volume of 255L at 40.0 C and 1.25 atm.
I used the formula P1xV1/T1 = P2xV2/T2
and kept the pressure at 0.75 atm but are you supposed to keep it as STP and switch it to kPa??
The answer I got was
(o.75atm)(V1)/243k = (1.25atm)(255L)/313k
V1 = 330L
Is this right??
