We need (i), a stoichiometrically balanced equation.......

Explanation:

C_8H_18(l) + 25/2O_2(g) rarr 8CO_2(g) + 9H_2O(l),

which I think is stoichiometrically balanced. If 15 mol of octane were completely combusted, we would get 120*mol of carbon dioxide, and 135*mol of water......

These (ii) represent masses of 120*molxx44.01*g*mol^-1=5.28*kg "carbon dioxide", and 135*molxx18.01*g*mol^-1=2.43*kg of "water".
