The Law of Definite Proportions

The law of definite proportions states that a given chemical compound always contains exactly the same proportion of elements by mass. This means that the ratio of the masses of the elements in a compound is always constant, regardless of the source or method of preparation of the compound.

Calcium Oxide Experiment

In the given experiment, 2.8 g of calcium oxide produced by heating limestone was found to contain 0.8 g of oxygen. This means that the ratio of the masses of calcium and oxygen in calcium oxide is 2.8:0.8 or 7:2.

When 1 g of oxygen was reacted with calcium, 3.5 g of calcium oxide were obtained. This means that the ratio of the masses of calcium and oxygen in calcium oxide is 3.5:1 or 7:2.

The results of the experiment clearly illustrate the law of definite proportions, as the ratio of the masses of calcium and oxygen in calcium oxide is constant and consistent with the law.

Conclusion

The law of definite proportions is an important concept in chemistry that helps to explain the composition of chemical compounds. The experiment discussed above provides a clear illustration of the law and its application in determining the ratios of elements in a compound.
