A sample of a paramagnetic salt contains `2.0 xx 10^(24)` atomic dipoles each of dipole moment `1.5 xx10^(-23) JT ^(-1)` . The sample is placed under a homogeneous magnetic field of 0.64 T and cooled to a temperature of 4.2 K. The degree of magnetic saturation achieved is equal to 15%. What is the total dipole moment of the sample for a magnetic field of 0.98 T and a temperature of 2.8 K ? ( Assume Curie's law)
