Answer:

Law of constant proportion states that, “a pure chemical compound always consists of the same elements that are combined together in a fixed (or definite) proportion by mass”. i.e. 3 g of carbon requires 8 g of oxygen to form carbon dioxide. ... 9 g of carbon require (3 X 8) 24 g of oxygen to form carbon dioxide

• In chemistry, the law of definite proportion, sometimes called Proust's law, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
• For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass.
• Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry
