How many Sr2 + ions are in a mole of Sr3 (PO4) 2

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

1 mol Sr3 (PO4) 2 (1 mol Sr2 + / 1 mol Sr3 (PO4) 2) (6.022x10^23 ions Sr2 + / 1 mol Sr2+) = 6.022x 10^23 Sr2 + ions
