The number of moles of Cl atom is calculated by use of avogadro constant = 1 moles = 6.02 x10^23
what about 3.01 x10^24
(3.04 x10^24)/ ( 6.02 x 10^23) = 5 moles
5 moles is for CL atom what about CL2 in MgCl2 = 2 x 5 =
10 moles

Answer: 10 moles
To find how many moles, you need to divide the number of atoms with 6.02 * 10^23. Since every magnesium chloride has two chlorine atoms, you need to multiply it by 2. The calculation would be: 3.01×10^24 * 2 / 6.02 * 10^23= 10 moles
