Two dilute solutions, A and B are prepared by dissolving two completely dissociable solutes, MA (Mol wt. X) and M ^ A ₂ (Mol wt. 2X) in water, respectively. Each solution contains W₂ g of the respective solute, dissolved in W₁ g of water. If the elevation of boiling point of A and B are measured to be T_b(A) and T_b(B) respectively, the ratio T _b( ~A ) / T _b( ~B ) would be
