b) The standard enthalpy change of combustion (i.e. the heat change) of sucrose is -5644 kJ mol-¹. Calculate the energy released when one sweet containing 6.70 g of sucrose is completely burnt. c) A man needs to consume about 2500 dietary calories (i.e. 2500 kcal) per day. Given that 1 kJ = 0.239 kcal, how many sweets would a man have to consume in order to meet his daily calorific requirement?
