Asample 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?

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.

grams of carbon require grams of oxygen

grams of carbon will require oxygen

grams of carbon will require oxygen

i think that the best answer would be c.

tell me if im wrong : )
