The density of a 10.0% by mass of KCl solution in water is 1.06 g/mL. Calculate molarity, molality and mole fraction of KCl in the solution.

Relation between molarity and molality|Mole fraction |Problem on mixing of solution

Assertion: For calculating the molality or the mole fraction of solute, if the molarity is known, it is necessary to know the density of the solution. Reason: Molality, molarity and the mole fraction of solute can be calculated from the weight percentage and the density of the solution.

Both molality and mole fraction are independent of temperature.

Calculate the molality and mole fraction of the solute in an aqueous solution containing 6g of urea per 500g of water (Mol. Mass of urea = 60)
