What is the mole fraction of 2 molarurea hydro solution?

Answer»

2.5 m solutionmeans thesolutioncontains2.5 molesof thesolutein 1000 g of solvent!!!. So the no.ofmolesofSolute=2.5. Now if we take the solvent as water the no.ofmolesof solvent =Weight/Mol.Wt =1000/18 =55.56. Thereforemole fractionof thesolute= No.ofmolesofSolute/Totalmoles=2.5/58.06= 0.04306

he did hame 2.5 molar urea hydro ka answer malum tha
