As per definition, Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at constant pressure.
molar mass of H2C2O4 is 90.03 g mol−1 (As per Wikipedia)
1g of anhydrous oxalic acid is burnt at 25 °C , the amount of heat liberated is 2.835 kJ
then when 90.03 g of anhydrous oxalic acid is burnt at 25 °C , the amount of heat liberated is 2.835*90.03= 255.23 kJ
So heat of Combustion is 255.23 kJ/mole
hope it helps u!!!!
