Question

Calculate the volume of carbondioxide produced by the combustion of 40 ml of acetone vapours in presence of excess of oxygen?

• A. 12 ml
• B. 1.20 ml
• C. 120 ml
• D. 11.2 ml

Answer 1

The correct option is C 120 ml

Combustion reaction of acetone can be written as:

$C{H}_{3}COC{H}_3+\frac{8}{2}{O}_2\to 3C{O}_2+3H_{2}O$

$1$ ml of acetone on combustion produces $3$ ml of carbon dioxide therefore, $40$ ml of acetone will produce $120$ ml of carbon dioxide on combustion.
