Interpretation Introduction
Interpretation:
The compound having the molecular mass of
Concept introduction:
The empirical formula of any chemical compound is shortest positive integer ratio of the atoms that are present in the compound. The empirical formula does not tell about the structure or the arrangement of atoms in the compound.
The arrangement of the molecules is depicted by the structural formula of the compound.
