Calculate mole fraction of solute in its 2 molal aqueous solution.

conc. of solution= 2molal= 2M

hence 2 moles of a solute are present in 1000 gram of water

W of water is 1000g

no. of moles in water= 1000/18

= 55.56 mol

total moles of solution= n of water+ n of solution=55.56+2 =57.56 mol

mol fraction of a solute=no. of moles of solute/ total moles in solution = 2/57.56 = 0.0347
