Question:

Mass susceptibility of Sr₂MnMoO₆ (molar mass 422.114 g/mol) was measured as a function of temperature, from which the Curie constant, C_m, was obtained by leastsquares fitting as C_m = 1.306×10⁻⁴m³ K/kg. Determine the oxidation states of Mn and Mo. Select an expression for the Curie constant C in Equation (9.19). Replace μ_eff in it with μ_eff/μ_B so that μ_eff is now in Bohr magnetons. Assuming two magnetic atoms performula, Mn and Mo, calculate the number N of these atomsin one kilogram of the sample.

Equation (9.19)
