Equal amounts of a solute are dissolved in equal amounts of two solvents `A` and `B`. The lowering of vapour pressure of solution `A` has twice the lowering of vapour pressure for solution `B`. If `Mw_(A)` and `Mw_(B)` are the molecular weights of solvents `A` and `B`, respectively , then
a.`Mw_(A) = Mw_(B)` , b. `Mw_(A) = Mw_(B)//2`,
c.`Mw_(A) = 4Mw_(B)`, d. `Mw_(A) = 2Mw_(B)`

Equal mass of a soute are dissolved in equal mass of two solvents A and B and formed very dilute solution. The relative lowering of vapour pressure for the solution B has twice the relative lowering of vapour pressure for the solution A. If m_(A) "and" M_(B) are the molecules mass of solventds A and B respectively, then :
