$\mathrm{Fe}$ has a density of $7.87 \mathrm{~g} . \mathrm{cm}^{-3}$, atomic mass of $55.84 \mathrm{~g} . \mathrm{mol}^{-1}$ and net magnetic moment per atom of $2.22$ Bohr magnetons ( $\mu_{B}$ ). The saturation magnetization of $\mathrm{Fe}$ in $\mathrm{A.m}^{-1}$ is $\_\_\_\_$ $\times 10^{5}$ (rounded off to one decimal place).
Given: $\mu_{B}=9.27 \times 10^{-24} \mathrm{~A} . \mathrm{m}^{2}$, Avogadro number $=6.023 \times 10^{23} \mathrm{~mol}^{-1}$
