As we have learnt,

 

susceptibility above curie temperature -

\chi _{m}= \frac{C}{T-T_{c}}

- wherein

(T>Tc)

 

 As magnetic susceptiblity x_m \propto \frac{1}{T}, therefore

\\*\frac{x_2}{x_1} = \frac{T_1}{T_2} \Rightarrow \frac{x_2}{0.0060} = \frac{273-73}{273-173} = \frac{200}{100} = 2 \\\\* x_2 = 2\times 0.0060 = 0.0120
