Homework Help: HELP

Posted by Chemistry on Thursday, January 27, 2011 at 6:40am.

Calculate the change in energy when 665.0 g of CH3OH(g) completely reacts at a constant temperature of 300 K and constant pressure of 0.95 atm. R = 8.314 J/mol*K and R = 0.08206 atm*L/mol*K

So i used the formula
change in energy = change in H - nRT

90.7-51.9-38.8

its wrong i need help
