A sample of ascorbic acid (vitamin c) is synthesized in the laboratory. It contains 1.5 grams of carbon and 2.00 grams of oxygen. Another sample of ascorbic acid isolated from citrus fruits contains 6.35 grams of carbon. How many grams of oxygen does it contain? Which law you assuming in answering this question?

(2*6.35/1.5) = 8.467 g
law of definite proportion or constant proportion.

Use the gram ratio between carbon and oxygen to solve this problem. There are other ways to solve it too. The law applied here is "Definite Proportion", meaning - ratio remains the same between the atoms in the compound, either by the atom count or the mass count.

(6.35/1.5) x 2.00.
Law of constant composition.
