Q)

A sample of paramagnetic salt contains $2.0 \times 10^{24} $ atomic dipoles each of dipole moment $1.5 \times 10^{-23}\; J/T$. the sample is placed under a homogeneous magnetic field of $0.64 \;T$ and colled 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 curies's law)

$\begin{array}{1 1} 1.033\;J/T \\ 10.335\;J/T \\ 1.0335\;J/T \\ 10.335\;T/J \end{array} $
