By Anne Marie Helmenstine, Ph.D. Molecular Equation Definition: A molecular equation is a balanced chemical equation where the ionic compounds are expressed as molecules instead of component ions. Examples: KNO 3 (aq) + HCl(aq) â KCl(aq) + HNO 3 (aq) is an example of a molecular formula.
Say that we want to calculate the molecular weight of water. The molecular weight is the sum of the atomic weights of the atoms in the molecule. We can go about our calculation by making a table. We list the atoms in the molecule down the left.
