Question

carbon dioxide contain carbon to Oxygen in a 3:8 (12:32) ratio,if 5 gram of co2 react with gram 32 gramof oxygen then then how many gram of cor2 is ​

Answer 1

Answer:

The atomic weight of Carbon atom=12

The atomic weight of Oxygen atom=16

Hence the atomic weight of carbon and oxygen atoms are constant

In CO

2

, the mass of carbon is 12 whereas that of oxygen is 32. Hence the ratio of their masses is 12:32=3:8

However, this fact is not justified by the constant atomic mass of carbon and oxygen. Hence both the statements are correct but the reason is not a correct explanation for the assertion
