Question by Andie: Support with empirical and molecular formulas?
The ratio of carbon atoms to hydrogen atoms to oxygen atoms in a molecule of THC (tetrahydrocannabinol) is 11:15:1. The molecular mass of THS is 326 g/mol. What is the molecular formula for THC?

Best answer:

Answer by bob_the_chemist

which is 163 / 326 or 1/2 molar mass so there are two empirical units in a mole of the compound

the molecular formula is then two x the empirical formula or
