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: $Cu_2O\text{ and }CuO$

We are given:

Mass of oxygen in CO = 13.6 grams

For carbon monoxide (CO):

Applying unitary method:

16 grams of oxygen are reacting with 12 grams of carbon

So, 13.6 grams of oxygen will be reacting with = $\frac{12}{16}\times 13.6=10.2g$ of carbon

For carbon dioxide (CO_2)

Applying unitary method:

12 grams of carbon are reacting with 32 grams of oxygen

So, 10.2 grams of carbon will be reacting with = $\frac{32}{12}\times 10.2=23.31g$ of oxygen

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