Molar Heat of Combustion | Definition, Equation & Formula
2023年11月21日 · In the international system, the molar heat of combustion values are defined in kilojoules per mole (KJ/mol). The kilojoule is a unit of energy and corresponds to 1000 or {eq}10^{3} {/eq} Joules (J).
The heat of combustion of ethane, C2H6, is 1560 kJ/mol. What is …
The problem asks us to determine the heat of combustion of ethane expressed in kJ per gram or kJ/gram. We need to convert the moles into grams which can be performed by using the molar mass of ethane. Therefore, the molar mass of ethane is our conversion factor to convert the heat of combustion from kJ/mol to kJ/gram. Answer and Explanation: 1
