A certain mass of carbon reacts with 13.6 g of oxygen to form carbon monoxide. grams of oxygen would react with that same mass of carbon to form carbon dioxide, according to the law of multiple proportions.

The mass of oxygen that will react with same amount of carbon as in carbon monoxide is 23.31 grams.

Explanation:

Law of multiple proportions states that when two elements combine to form two or more compounds in more than one proportion. The mass of one element that combine with a given mass of the other element are present in the ratios of small whole number. For Example:

We are given:

Mass of oxygen in CO = 13.6 grams

Applying unitary method:

16 grams of oxygen are reacting with 12 grams of carbon

So, 13.6 grams of oxygen will be reacting with = of carbon

Applying unitary method:

12 grams of carbon are reacting with 32 grams of oxygen

So, 10.2 grams of carbon will be reacting with = of oxygen

Hence, the mass of oxygen that will react with same amount of carbon as in carbon monoxide is 23.31 grams.
