A sample of paramagnetic salt contains \( 2.0 \times 10^{24} \) atomic dipoles each of dipole moment \( 1.5 \times 10^{-23} \mathrm{~J} / \mathrm{T} \). The sample is placed under a homogeneous magnetic field of \( 0.64 \mathrm{~T} \), and cooled to a temperature of \( 4.2 \mathrm{~K} \). The degree of magnetic saturation achieved is equal to \( 15 \% \). What is the total dipole moment of the sample for a magnetic field of \( 0.98 \mathrm{~T} \) and a temperature of \( 2.8 \mathrm{~K} \) ? (Assume Curie's law)
