Okay this is a combustion reaction and as per eqn below----

C+0²—→ co2

That means 1mole carbon needs 1mole oxygen gas(o2) to give 1mole carbon dioxide, okay the above statement can also be said like---- 12 g C needs 16×2 gm (32g) of oxygen to give 44gm of co2

1 gm C= 1/12 x 44= 3.67gm CO2

So 18gm C=18×3.67 =66.00gm

So the amount of carbon dioxide form would be 66.00gm
