Interpretation:
The meaning of percent composition should be explained.
Concept introduction:
Molar mass of the compound is equal to the sum of
Explanation of Solution
The ratio of mass of each element to the total mass of individual elements present in the compound multiplied by 100 is known as percentage composition.
The percentage composition of a compound represents its composition of elements (all) present in it.
The mathematical expression of percentage composition is:
The ratio of mass or amount of element to the total mass of compound is multiplied by 100 to represents in terms of percentage.
For an example:
Let mass of element A = 10 g
Mass of total compound = 20 g
Thus,
= 50 % A
Hence, one can say that the percentage composition of 50 % A, there is 50 g of A is present in the compound if total compound has mass of 100 g.
