Then, Molecular mass of the acid = Equivalent mass of the acid x Basicity of the acid. The basicity of an acid is equal to the number of ionizable hydrogen atoms in a molecule of the aci..
Calculation of Valency
The number of valence electrons is the valency of the element. The valency of an element can also be calculated by finding the number of electrons required to complete octet (8)i.e., 8 - Number of valence electrons = Valenc..
