Convolution theorem

find the inverse Laplace transform of the given function by using the convolution theorem. 9.F(s)=1(s+1)2(s2+4). Iron can be converted to Fe2O3 according to the reaction below. How much heat (in kJ) is required to convert 10.5 g of iron to Fe2O3? 2Fe(s) + 3CO(g) → Fe₂O₃(s) + 3CO₂(g)  ΔH = 26.8 kJ/mol
