Final answer:
The question is about stoichiometry and enthalpy changes in chemistry, specifically the heat produced by combustion of a particular isomer of C8H18.
Step-by-step explanation:
The question is asking about the subject of stoichiometry and enthalpy changes in chemistry. The student is given the information that the combustion reaction of a particular isomer of C8H18 produces 5113.3 kJ of heat per mole of C8H18(g) consumed, under standard conditions.
To calculate the amount of heat produced by combustion of a given sample, we need to use the stoichiometry of the combustion reaction and the amount of substance consumed. We can convert the given information (per mole) to the amount of heat produced by multiplying it with the number of moles of the substance consumed.
