: MOLECULAR WEIGHT 
A compound is made up of two or more elements combined in a definite ratio that is 
represented by a molecular formula. Each of these elements has a certain atomic 
weight, which can be found in the periodic table. The sum of the atomic weights of 
the atoms in the molecular formula is called the formula weight or molecular 
weight or formula mass. We will use the term molecular weight for this number in our 
work. Here are three examples of molecular weight determination:
