A solution has two solutes, A and B. Molarity of solute A is 0.5 M and of solute B is 1 M . What should be the density of solution (in gm/ml) so as numerical value of molality of both solute is equal to numerical value of their molarity?
(Molecular weight of solute A and B are 180 and 60 respectively).

Let volume be 1L ( 1000 ml ) For molarity and molality to be equal numerical Value of volume (in L ) is equal to Mass of solvent (in kg) 1 = 1000 1000 d − 0.5 × 180 − 1 × 60 ​ d = 1.15 gm / ml
