A sample of ascorbic acid (vitamin C) is synthesized in the laboratory. It contains 1.50 g of carbon and 2.00 g of oxygen. Another sample of ascorbic acid isolated from citrus fruits contains 6.35 g of carbon. How many grams of oxygen does it contain? Which law are you assuming in answering this question?

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:

\(8.467\) 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.

\(1.50\) grams of carbon require \(2.0\) grams of oxygen

\(1.0\) grams of carbon will require oxygen

\(= \frac{2}{1.5}\)

\(6.35\) grams of carbon will require oxygen

\(\frac{2}{1.5}*6.35\\= 8.4666\\= 8.467\)
