Question

How do I calculate the amount of heat will be required to make 100.0kg of a compound, the molar enthalpy is -63kj/mol for the same compound

Answer 1

You need the molar mass of the compound if that is the molar enthalpy of formation of the compound.
100,000 g/molar mass = ? mols compound.
What reaction is that -63 kJ/mol for?
