A salt mixture (1.0 g) contains 25 wt\% of $\mathrm{MgSO_4}$ and 75 wt\% of $\mathrm{M_2SO_4}$. Aqueous solution of this salt mixture on treating with excess $\mathrm{BaCl_2}$ solution results in th precipitation of 1.49 g of $\mathrm{BaSO_4}$. The atomic mass of M in $\mathrm{g\,mol^{-1}}$ (rounded off to two decimal places) is ____. (Given: the atomic masses of $\mathrm{Mg}$, $\mathrm{S}$, $\mathrm{O}$, $\mathrm{Ba}$ and $\mathrm{Cl}$ are $24.31, 32.06, 16.00, 137.33$ and $35.45\,\mathrm{g\,mol^{-1}}$, respectively)
(a)1
(b)3
