Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 6.10 moles of magnesium perchlorate, Mg(ClO4)2.

Answer 1

From formula => 1 mole Mg + 2 moles Cl + 8 moles O
If you need the numerical number of atoms of each, remember Avogadro's Number => 1 mole contains 6.02E+23 then n-moles would be => n(Avogadro's No)
