Equation is: CH4(g) + 2O2 (g) ---> CO2 (g) + 2H2O (l) Enthalpy Change = -213 kcal ​ I had no problem with the first answer. Using \[Enthalpy Change = Heat of the Reaction / mols\], I converted the -213 kcal to kJ (-891.192 kJ), 27.0 g of CH4 to 1.6875 moles of CH4, and then solved for the Heat of the Reaction. I'm having a bit of trouble for part 2, finding the mass of O2 when 950 kJ of heat are released, though. I'm not sure if I'm supposed to do the same as the above, except p...
