How do I calculate Molar Heat of Reaction? How do I calculate avg Molar Heat of Reaction? Attached is the given equation but I'm unsure of how to plug it in Experiment #1 Experiment #2 Initial Temperature, T. 20.5 20.5 Final Temperature, Tf 32.2 42.3 Temperature Change, AT 11.7 21.8 Mass of magnesium, mmg 0.138 g 0.241 g Experiment #1 Experiment #2 Q in joules (J) from Eq. 1 1.65 J 5.38 J Q in kJ (conversion factor = 1 kJ/1000 J) 0.00165 kJ 0.00538 kJ Moles of Mg from Eq. 3 0.00567901 mol 0.0099177 mol Molar Heat of Reaction, AHrxn (kJ/mol), from Eq. 2 ? ? Average Molar Heat of Reaction, AHxn (kJ/mol) ? The heat of the reaction has the same magnitude as Q, but opposite sign. To calculate the molar heat of reaction, AHrxn, the heat of the reaction must be divided by the num- ber of moles of Mg, nmg- AHxn Eq. 2 NMg
