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"#.
