What is the magnetic moment of K3[FeF6] ?

the formula is sqrt(n(n+2) here the ''n'' is the number of unpaired electrons present in a metal.here Fe has ooxidation  state +3 and it has 5 unpaired electrons...so we can take n=5

therefore the answer will be 5.91 B.M

hai my dear pithre the magnetic momentum of K3[FeF6]  is 5.9B ok,,,,,

Dear Prasanth

IN THE COMPLEX K3[FeF6] the metal element is Ferrous .... So the oxidation state of the Ferrous is +3 ..

I THINK U KNOW THAT Fe+3 have 5 unpaired d-electrons So the magnetic moment of K3[FeF6}

========================= (35)0.5 ===> 5.91 bm
