In a constant volume calorimeter, 3.5 g of a gas with molecular weight 28 was burnt in excess of oxygen at 298 k. The temperature of the calorimeter was found to Increase from 298 k to 298.45 k due to the combustion process. Given that the heat capacity of the calorimeter is 2.5 KJ/K. The Numerical value for the enthalpy of combustion of the Gas in KJ /Mole is

Equimolar mixture of D–glucose and D – glucose
Equimolar mixture of D – glucose and D – galactose
Equimolar mixture of D – glucose and D – fructose
Equimolar mixture of D – galactose and D – galactose
Lactose is made by a glycosidic bond between β-D-Galactose and α-D-Glucose. Hence, they are present in the equimolar ratio in each molecule of lactose.
