Question
Chapter 2, Problem 4CGP
Interpretation Introduction
Interpretation:
The mole ratio concept is more useful than the atom or mass concept, is to be discussed.
Concept introduction:
Mole is generally a link between the mass and the number of atoms and molecules.Moles enable measurement in larger units and provide a standard for the number of units, rather than atoms or molecules.
The mass ratio is used to find the ratio of the proportions of the components by mass and
