12.976 g of lead combines with 2.004 g of oxygen to form `PbO_(2). PbO_(2)` can also be produced by heating lead nitrate and it was found that the percentage of oxygen present in `PbO_(2)` is 13.38 %. With the help of given informations, illustrate the law of constant composition.

6.488 g of lead combines directly with 1.002g of oxygen to form lead peroxide. Lead peroxide also can be prepared by heating lead nitrate. It was found that the percentage of oxygen present in lead peroxide prepared by the second experiment is 13.38. Use this data to illustrate the law of definite proportions.
