Answer : The mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,

As we are given:

According to the law of conservation of mass,
Total mass of
= Mass of
+ Mass of C
Total mass of
= 2.67 + 1 = 3.67 g
Now we have to calculate the mass of
and C.

and,

Therefore, the mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
