The molecular weight is ALWAYS a whole-number multiple of the empirical formula weight.

Question

Quizplus · Accepted Answer

This is true because the molecular weight is the sum of the atomic weights of all the atoms in a molecule, while the empirical formula weight is the sum of the atomic weights of the atoms in the empirical formula. Since the molecular formula is always an integer multiple of the empirical formula, the molecular weight will also be an integer multiple of the empirical formula weight.
