Q57. A first row transition metal with highest enthalpy of atomisation, upon reaction with oxygen at high temperature forms oxides of formula $\mathrm { M } _ { 2 } \mathrm { O } _ { \mathrm { n } }$ (where $\mathrm { n } = 3,4,5$ ). The 'spin-only' magnetic moment value of the amphoteric oxide from the above oxides is $\_\_\_\_$ BM (near integer) (Given atomic number: $\mathrm { Sc } : 21 , \mathrm { Ti } : 22 , \mathrm {~V} : 23 , \mathrm { Cr } : 24 , \mathrm { Mn } : 25 , \mathrm { Fe } : 26 , \mathrm { Co } : 27 , \mathrm { Ni } : 28 , \mathrm { Cu } : 29 , \mathrm { Zn } : 30$ )
