A sample of paramagnetic salt contains `2xx10^(24)` atomic dipoles, each of moment `1.5xx10^(-23)JT^-1`. The sample is placed under a homogeneous magnetic field of `0.64T` and cooled to a temperature of `4.2K`. The degree of magnetic saturation archieved is equal to `15%`. What is the total dipole moment of the sample for a mangetic field of `0.98T` and a temperature of `2.8K`. (Assume Curie's law).

It is known from Curie's law that magnetic moment (m) of a paramagnetic sample is directly proporational to the ratio of the external magnetic field (B) to the absolute temperature (T). A sample of paramagnetic salt contains 2.0 xx 10^(24) atomic dipoles each of dipole moment 1.5xx 10^(-23) JT^(-1) . Sample is placed under a homogeneous magnetic field of 0.84 T and cooled to a temperature of 4.2. The drgree of magnetic saturation achevied is equal to 15% . You may assume that 85% dipoles are randomly oriented and do not contributes to the magnetisation .
