Concept introduction:
There are many ways of finding concentration of an element in a compound or a component in a mixture. Mass percent is one of those ways in which the concentration can be calculated.
The mass percent of an element in any compound is found as:

Answer to Problem 79A
Law of multiple proportion is used to compare CO and
Mass percent of oxygen in CO and
Explanation of Solution
Law of multiple proportions states that when two elements are combined to form more than one compound, the weight of one element that combines with the fixed weight of the other element are in a small simple ratio of whole numbers.
Mass percent of oxygen is calculated as:
The mass percent of oxygen in
Law of multiple proportion explains the relation, when the two reactant react to form more than one compounds. It states that when two elements are combined to form more than one compound, the weight of one element that combines with the fixed weight of the other element are in a small simple ratio of whole numbers.
The mass percent of the element that constitutes higher molecular weight in the compound, will be higher than the other element.
