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

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
