Question 1

What is a Molecular Formula?

Accepted Answer

The molecular formula gives the actual number of each type of atom in a single molecule of a compound. It is a whole-number multiple (n) of the empirical formula, where n = Molar mass / Empirical formula mass.

Question 2

How does the Molecular Formula work?

Accepted Answer

Determine the empirical formula and its formula mass Then: Measure or look up the actual molar mass Then: n = Actual molar mass / Empirical formula mass Then: Molecular formula = empirical formula × n.

Question 3

Can you give an example of how to use the Molecular Formula?

Accepted Answer

Example: Input Empirical CH₂O (mass 30) · Actual molar mass 180 gives a result of n=6 → Molecular formula C₆H₁₂O₆ (glucose) (180/30=6).
