Question

Quizplus · Accepted Answer

According to the law of multiple proportions, the ratio of the masses of oxygen that combine with a fixed mass of carbon to form carbon monoxide and carbon dioxide is 1:2. Since 23.3 g of oxygen forms carbon monoxide, 46.6 g (23.3 g x 2) of oxygen would form carbon dioxide.
