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

What orbital do the transition metals finish their electron configuration in
PIT_PIT [208]

Answer:

d orbitals

Explanation:

Transition  metals are generally known as d-block elements. The electronic configuration of all transition elements finish in a d-orbital weather they are first row, second row or third row transition elements. This is the thread that holds all the elements of the transition series together.

This is why elements of the transition series are generally called the d-block elements.
