3 The magnetic susceptibility of platinum is 2.61×10-4. The density of platinum is 21450 kg m-3 and its relative atomic mass is given by 195.09 g mol-1. Calculate its molar susceptibility (in m³ mol-¹) and its mass susceptibility (in m³ kg-1). Using Appendix A, translate these results into cgs units to find the molar susceptibility in emu mol-¹ and the mass susceptibility in emu g-¹. To understand why the magnetic susceptibility of platinum, a metal, is temperature independent (in contrast with Curie's law), see chapter 7.
