Q) An element forms two oxides containing 50% and 40% of the element by mass. Prove that the results are in agreement with the law of multiple proportion.?
Verified Answer
Q) An element forms two oxides containing 50% and 40% of the element b...
In one oxide:
50g of element combines with 50g of oxygen.
Therefor, 1g of element will combine with 1g of oxygen
In the other oxide:
40g of element will combine with 60g of oxygen.
Therefore, 1g of element will combine with 64/40 or 1.5g of oxygen.
Thus, the weights of oxygen that combines with 1g of the element in the two oxides are in the ratio of 1:1.5 or 2:3, which is a simple ratio. This illustrates the law of multiple proportions.

Law of Multiple Proportions
The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole numbers.
Given Data
- Element forms two oxides containing 50% and 40% of the element by mass.
Calculation
Let's assume the element is X.
- Let the first oxide be X2O, containing 50% of X by mass.
- Let the second oxide be XO, containing 40% of X by mass.
According to the law of multiple proportions, the ratio of masses of X in the two oxides should be a small whole number.
- Mass of X in X2O = 50%
- Mass of X in XO = 40%
To find the ratio, we can set up a proportion:
50/40 = 5/4
This ratio simplifies to 5:4, which is a small whole number.
Conclusion
The results obtained (5:4 ratio) are in agreement with the law of multiple proportions, proving that the element forms two oxides in a fixed ratio by mass. This consistency supports the fundamental principle of chemical combination and helps in understanding the stoichiometry of compounds.
