In a constant volume calorimeter, 3.5g of a gas with molecular mass 28 was burnt in excess oxygen at 298.0 K. the temperature of the calorimeter was found to increase from 298.0K to 298.45K, due to the combustion process. Given, that the heat capacity of the calorimeter is 2.5kJ*K^(-1) , what will be the value of enthalpy of combustion of the gas?

When 1.0g of a compound (molecular weight=28) is burnt in a bomb calorimeter, the temperature of the calorimeter rises from 25^(@)C to 25.45^(@)C . Calculate the heat that evolves when 1 mol of this compound is completely burnt (C_(cal)=2.5kJ*K^(-1)) .
