Two compounds each containing only tin and oxygen had the following composition: {:(,"Mass % of tin","Mass % of oxygen"),("Compound A",78.77,21.23),("Compound B",88.12,11.88):} Show how this data illustrate the law of multiple proportions?

Answer»

Solution :In compound A
21.23 parts of oxygen combine with 78.77 parts of tin 1 part of oxygen combines with 78.77/21.23=3.7 parts of tin
In compound B
11.88 parts of oxygen combine with 88.12 parts of tin
1 part of oxygen combines with 88.12/11.88=7.4 parts of tin Thus, the mass of tin in compound. A and B which combine with a fixed mass of oxygen are in the ratio of 3.7:7.4
or 1:2. this is a SIMPLE ratio. HENCE, the DATA ILLUSTRATE the law of MULTIPLE proportions.
