Question

Three compounds containing potassium and oxygen are compared. Analysis shows that for each 1.00g of o, the compounds have 1.22g, 2.44, and 4.89 g og K, respectively. Show how this data supports the law of constant composition

Answer 1

According to the law of constant composition;

• the first compound, the constant mass ratio of O to K is 1 : 1.22
• the second compound, the constant mass ratio of O to K = 1 : 2.44
• the third compound, the constant mass ratio of O to K = 1 : 4.88

What is the law of constant composition?

The law of constant composition states that pure samples of a given compound contain the same element combined in the same ratio by mass.

The law is seen practically in that given a compound such as water, all pure samples of water irrespective if the source contains hydrogen and oxygen i a mass ratio of 2 : 1.

Considering the compounds containing potassium and oxygen:

Analysis shows that for each 1.00g of O, the compounds have 1.22g, 2.44, and 4.89 g of K, respectively.

For the first compound, the ratio of mass ratio of O to K = 1 : 1.22

For the second compound, the ratio of mass ratio of O to K = 1 : 2.44

For the third compound, the ratio of mass ratio of O to K = 1 : 4.88

Therefore, this data  supports the law of constant composition.
