Question

the enthalpy of combustion of glucose 2840 kilo joule per mole what is its calorific value

Answer 1

The amount of heat produced by complete combustion of 1 g substance is called calorific value.

∵ 180 g glucose gives heat = 2840 kJ

∴ 1 g glucose will give heat = 2840 / 180 kJ

                                            = 15.78 kJ/g
