1.81 x 10²⁴ atoms He


You can find the amount of atoms by multiplying the given moles by Avogadro's Number. This number represents the amount of atoms per 1 mole. It is important to arrange the ratio in a way that allows for the cancellation of units.

Avogadro's Number:

6.022 x 10²³ atoms = 1 mole

3 moles He           6.022 x 10²³ atoms
 x    =  1.81 x 10²⁴ atoms He
                                       1 mole
