Question

The common salt was obtained from two different sources. In one sample, the percentage of chlorine was found to be 60.75%. In the second sample, 3.888g of chlorine were present in 6.4g of the salt. Show that these data are in accordance to the law of constant proportions.

Answer 1

Explanation:

The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass. For example, pure water will always contain hydrogen and oxygen in a fixed mass ratio (a gram of water consists of approximately 0.11 grams of hydrogen and 0.88 grams of oxygen, the ratio is 1:8).
