If 2.4m^3 of a gas initially at STP is compressed to 1.6m^3 and its temperature is raised to 30degreesC, what is the final pressure?
I thought this would be a easy one but my answers are coming out and don't look right.
I used pV=nRT
p=1.6m^3
V=2.4m^3
R=8.31J(mol*k) --- universal gas constant
T=30degreesC
So I plugged everything into the equation pV=nRT and solved for n and got .015403, it didnt look right so I converted 30degreesC to K (which equals 303.15K) then solved for n again and got .00154, which I am sure is also wrong.
Am I using the wrong equation?? There was only a few to choose from in the book:
pV/T=Constant, pV=nRT, pV/T=NKsubB
Please Help thanks
