According to the following reaction, how much energy is evolved during the reaction of 32.5g B2H6 and 72.5g Cl2? The molar mass of B2H6 is 27.67g/mol.

B2H6(g)+6Cl2(g)----->2BCl3(g)+HCl(g)

Delta H reaction=-1396

1396 WHAT?
Find the limiting reagent. Then
1396 whatever x (mass limiting reagent/molar mass limiting reagent) = ?
