A chemist decomposes several samples of carbon monoxide into carbon and oxygen and weighs the resultant elements. The results are shown below:


Sample

Mass of Carbon (g)

6,12,18

Mass of Oxygen

(g) 8,16,24

Part A

Do you notice a pattern in these results?

The mass of carbon and oxygen pair from the decomposition of carbon monoxide has an obvious pattern of 3 carbon : 4 oxygen. This can be explained by the balanced chemical equation of the decomposition of CO. 

6g carbon : 8g oxygen
12g carbon : 16g oxygen
18g carbon : 24g oxygen

These all results to a common ration of 3g C is to 4g O2
