Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 3.00 moles of magnesium perchlorate, mg(clo4)2. express the number of moles of mg, cl, and o atoms numerically, separated by commas.

The  number  of  moles  of   magnesium, chlorine  and oxygen   atoms  in 3.00  moles  of  magnesium   perchlorate (MgClO4)2  is  3,6, 24  respectively

calculation

find  the total  number of  each atoms  in   Mg(ClO4)2

that is  Mg = 1 x1 = 1 atoms
             Cl  =  1 x2  = 2 atoms
              O =    4  x2  = 8  atoms
then  multiply the total number of  each atom  with   3  moles

that  is  Mg =  1  x3  =  3moles
               Cl  =  2  x3 =  6 moles
                O =   8 x3  =  24  moles
