Empirical formula is related to molecular formula by:
Correct answer: B. Molecular formula = n(empirical formula)
- A. Molecular formula = empirical formula/n
- B. Molecular formula = n(empirical formula)
- C. Molecular formula = 2n(empirical formula)
- D. Empirical formula = n (Molecular formula)
Explanation
Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule.
