Have you heard of Avogadro's constant?

The Avogadro constant, usually denoted by NA or L is the factor that, multiplied by the amount of substance in a sample, measured in moles, gives the number of constituent particles in that sample. Its unit is the reciprocal of mole, and it is defined as NA = 6.02214076×10²³ mol⁻¹.

3 mols x (6.023x10^23) = 18.069x10^23 molecules in propane
