(a)
Interpretation: The heat of combustion per gram needs to be determined for the mentioned hydrocarbons.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.
(b)
Interpretation: The same calculations as in part (a) needs to be done for ethanol.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.
(c)
Interpretation: Whether the fuel capability of hydrocarbon is more or less than ethanol needs to be determined.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.
