Expert Answer

Co(28) Co2+ = d3

There are 3 unpaired electrons in [Co(H2 O)6]2+ and calculated value of magnetic moment is 

straight mu equals square root of straight n left parenthesis straight n plus 2 right parenthesis end root ​ equals 3.87 space BM

Its experimental value is found to be 4.40 BM, due to some contribution of the orbital motion of an electron to the magnetic moment
