The spin-only magnetic moment (yso) can be calculated by the equation: piso-4 S(S +1), where S is the spin state. An equivalent equation is: jso= n(n+2), where n is the number of unpaired electrons. Note: 13 = 1.73 18 = 2.83 15 = 3.87 24 = 4.90 V35 = 5.92 1. What is the magnetic moment for (Fe(H:0).JSOA? 2. What is the magnetic moment for Cr(CO). ? 3. What is the magnetic moment for (NH4)2[CoBr.]? 100000! 4. What is the magnetic moment for [Rh(NH3).J(CIO4)3 ? 5. What is the magnetic moment for (Cr(en)](CIO);? 6. What is the magnetic moment for [Fe(bpy)3]SO.?
