A salt mixture (1.0 g) contains 25 wt% of MgSO₄ and 75 wt% of M₂SO₄. Aqueous solution of this salt mixture on treating with excess BaCl₂ solution results in the precipitation of 1.49 g of BaSO₄. The atomic mass of M in g mol⁻¹ (rounded off to two decimal places) is . (Given: the atomic masses of Mg, S, O, Ba and Cl are 24.31, 32.06, 16.00, 137.33 and 35.45 g mol⁻¹, respectively)
