Problem

Palmitic acid (C16H32O2) is a dietary fat found in beef and butter. The caloric content of palmitic acid is typical of fats in general. Write a balanced equation for the complete combustion of table sugar (sucrose, C12H22O11). What is the caloric content of sucrose in Cal/g? The standard enthalpy of formation of palmitic acid is –208 kJ/mol and that of sucrose is –2226.1 kJ/mol. [Use H2O(l) in the balanced chemical equations because the metabolism of these compounds produces liquid water.]
