Q. How do you find the empirical formula of a substance?
Calculate the empirical formula.
- In any empirical formula problem you must first find the mass % of the elements in the compound.
- Then change the % to grams.
- Next, divide all the masses by their respective molar masses.
- Pick the smallest answer of moles and divide all figures by that.

Q. What is the difference between an empirical and a molecular formula?
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, and structural formulas show how the atoms in a molecule are bonded to each other.
Q. Which of the following compound has the same empirical formula?
Answer: Multiple compounds can have the same empirical formula. Glucose, C6H12O6, contains carbon, hydrogen, and oxygen. The ratio of carbon to hydrogen to oxygen is 1:2:1.
Q. What is the empirical formula of a compound containing sulfur and oxygen if the compound is 50% sulfur by mass?
5. Therefore, the empirical formula of the compound is S1O2 or simply written as SO2.
