Question

24 g of carbon reacts with some oxygen
to make 88 grams of carbon dioxide.
Find out how much oxygen must have
been used.
(Ans. : 64.0)​

Answer 1

Answer:

64

Explanation:

As per the law of conservation a atom can not be created or destroyed .

Given,carbon =24g

Total Carbon dioxide made=88g

Therefore, 88-24=64

So, the oxgen added in reaction of carbon dixide is 64g

Answer 2

the reactant mass is equal to product mass.

hence,

24+X=88

X=88-24

X=64 grams of oxygen is needed to form 88 grams of carbon dioxide with 24 grams of carbon.
