A container made from 900g iron is 28.7L in size and has 1.00atm N2 inside. Then CH4 is burned to heat the container and the final pressure is 927 torr and 335K in temp. CH4 + 2 O2 --> CO2 + 2H2O dHrxn = -890 kJ SN2 = 1.04J/gC SFe = 0.4498 J/gC All heat from burning goes into container and gas. What was the mass of CH4 in grams required?
