The magnetic moment of a molecule can be calculated using the formula: = n n+2 Bwhere n is the number of unpaired electrons and B is the Bohr magneton approximately 9.274 x 10^-24 J/T .For FeCl3 in a high-spin state with five unpaired electrons, we can plug the values into the formula: = 5 5+2 B = 5 7 B = 35 BNow, we can multiply by the value of the Bohr magneton: 35 x 9.274 x 10^-24 J/T 5.92 x 9.274 x 10^-24 J/T 5.49 x 10^-23 J/TSo, the magnetic moment of FeCl3 in a high-spin state with five unpaired electrons is approximately 5.49 x 10^-23 J/T.
