Phosphorus forms several compounds with oxygen, including diphosphorus trioxide and diphosphorus pentoxide. a decomposition of a sample of diphosphorus trioxide forms 1.29 g phosphorus to every 1.00 g oxygen. the decomposition of a sample of diphosphorus pentoxide forms 0.775 g phosphorus to every 1.00 g oxygen. show that these results are consistent with the law of multiple proportions.

Results are consistent with law of multiple proportions.

Explanation:

Dalton's law of multiple proportions states that the elements can be combined to form more than one compound and do so in such a way that if we keep the quantity of one element as fixed, the quantity of the other element is added in such a way that they are obtained integer proportions.

Molar mass of oxygen is 16g per mole, molar mass of phosphorus is 31g per mole.

In the ratio between P and O is , that is consistent with the experimental result.

and for the ratio between P and O is that is also consistent with experimental results. In conclusion we can say that the results obtained are consistent with the law of multiple proportions.
