1.00 mol O2

Ti = 300K

Vi = 5.00L

4400 j of energy transfered by heat to the system

Vf = ?

Constant Pressure = 29.4 J/mol * K

So I set the problem up using Q = n(Constant Pressure)(Tf - T-i)

Solving for Tf I find that Tf is equal to 449.7K.

Then using equation (Vf - Vi) = (nR(Tf - Ti)) / P

Vf = ((1.00mol * 8.31 J/mol*K * 149.7K) / (1.013*10^5 N/m^2)) + 5.00L

I am getting Vf = 17.28 L

Can anyone tell me what I am doing wrong? My teacher told me the answer should be 7.52, could he of possibly meant 17.52?

Any help would be appreciated!
