Stearic acid (C18H36O2) is a typical fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, chances are that you are ingesting some fats that contain stearic acid. Calculate the heat (q) in kJ and kcal when 39.8 g of stearic acid is burned completely given that ΔH°f = -948 kJ/mol.
