Homework Statement
If 18.75 mol of helium gas is at 10.0C and a gauge pressure of 0.035atm, calculate a) the volume of the helium gas under these conditions. b) calculate the temp if the gas is compressed to half the voume at a gauge pressure of 1.00atm.
Homework Equations
PV=nRT
P1V1/T1 = P2V2/T2
Tk = Tc + 273
absolute press = gauge press +1atm
The Attempt at a Solution
V=nRT/P = (18.75mol * 8.315 J/mol K * 283K) / 1.35 atm = 3.27 *10^4 m3
Book answer = 0.323 m3
Haven't yet attempted part b, because haven't yet calculated V correctly. Anybody see where I went wrong? Thanks!
