 It contain oxygen atom calculated below
6.35gC x 2.00gO/1.50gC
 = 8.47g O 
  The law is that a sample of a pure substance is the same as any other sample of the pure substance no matter what the source is
hope it helps

Answer:

[tex]8.467[/tex] grams of oxygen

Explanation:

The law governing this problem is "The Law of Constant Composition "

As per this law, all compounds irrespective of their origin and source have the same composition and properties  in their purest form

It is a simple proportion and ratio related problem.

[tex]1.50[/tex] grams of carbon require [tex]2.0[/tex] grams of oxygen

[tex]1.0[/tex] grams of carbon will require oxygen

[tex]= \frac{2}{1.5}[/tex]

[tex]6.35[/tex] grams of carbon will require oxygen

[tex]\frac{2}{1.5}*6.35\\= 8.4666\\= 8.467[/tex]
