How much energy is evolved during the rxn of 32.5g of B2H6 and 72.5g of Cl2?

Molar mass of B2H6 is 27.62 g/mol

B2H6(g)+6Cl2(g)= 2BCl3(g)+ 6HCl(g)

Delta H rxn= -1396 kJ

I think the question probably stated that the -1396 is kJ/mole and not kJ. If it were kJ, then that would be the answer since is says that's the ∆H of the "reaction".
