How do you know how many atoms are in a sample?
So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. This is Mass → Moles . Once you have moles, multiply by Avogadro’s number to calculate the number of atoms. This is Moles → Atoms .
