Ok, here is what is given:
1.00 mol O2
Ti = 300K
Vi = 5.00L
4400 j of energy transferred 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!
