Reference no: EM13312668

A new artificial sweetener has been prepared in the laboratory (molar mass = 380 g/mol). The sweetener is tested in a bomb calorimeter to determine its energy content per gram. When 5.278 g of the sweetener are combusted in a calorimeter with a heat capacity of 17.63 kJ/°C a temperature increase of 1.82 °C is measured. What is the energy content (kJ/g) of this sweetener?
