In higher oxide
Metal = 80%
Oxygen = (100-80)% = 20%
Therefore, we can say that 4 parts of metal combines with 1 part of oxygen.
Now, 0.72 g of lower oxide on oxidation gives 0.8 g of higher oxide. It can be assumed that the mass percent of metal in 0.8 g is same as that of 0.72 g of lower oxide. So,
Mass of metal in higher oxide = (80/100) x 0.8 g = 0.64 g
If in 0.8 g of higher oxide 0.64 g is metal then mass of oxygen present in higher oxide will be (0.8 - 0.64) g = 0.16 g
Since, lower oxide contains the same mass of metal as that of higher oxide, we need to calculate the mass of oxygen in lower oxide.
Mass of oxygen in lower oxide = (0.72-0.64) g = 0.08 g
According to Law to multiple proportions if two elements combine with each other to form two different compounds then the ratio of masses of that element which combines with the other element whose mass is fixed in both the compounds, will be in small whole numbers. Now, in the given problem the mass of metal in both the oxide is fixed so, for the data to illustrate the law of multiple proportion the ratio of mass of oxygen in both the oxides should be in whole numbers.
Now, mass of oxygen in higher oxide : mass of oxygen in lower oxide = 0.16 : 0.08 = 2 : 1. Therefore, it can be said that the given data depicts law of multiple proportion.

The law of multiple proportions can be partly explained by the idea that?
The law of multiple proportions can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
Laws of chemical conbination?
The laws of chemical combination are fundamental principles that govern the relationships between the quantities of reactants and products in a chemical reaction. The three main laws are the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. The law of conservation of mass states that mass is conserved in a chemical reaction, meaning that the total mass of the reactants is equal to the total mass of the products. The law of definite proportions states that a compound always contains the same proportions of elements by mass. The law of multiple proportions states that when two elements combine to form multiple compounds, the mass ratios of the elements in the compounds are always in whole-number ratios.
What is multiple proportions?
The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. Two examples of the law of multiple proportions are carbon monoxide, CO, and carbon dioxide, CO2, and water, H2O, and hydrogen peroxide, H2O2.
What laws provided evidence for the existence of atoms?
The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.
What experimental evidence led to the formation of the law of multiple proportions?
Chemical analysis of many compounds led to this conclusion.
What pair of substances best illustrates the law of multiple proportions?
carbon monoxide and carbon dioxide

Who made the law of multiple proportions?
The law of multiple proportions was proposed by John Dalton in 1804; today this law has not a general validity.

Who developed the multiple proportions law?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
