Mole fraction of the solute in 1 molal aqueous solution is

What is the mole fraction of solute in 2.5m aqueous solution .

Calculate the molality and mole fraction of the solute in aqueous solution containing 3.0 g urea per 250 g of water (molecular mass of urea = 60g).

The expression relating molality and mole fraction of the solute in a solution is (molar mass of solvent= M_1 ):

The vapour pressure of the solvent decreased by 10 mm of Hg when a non volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the fraction of the solvent if a decrease in vapour pressure of 20 mm of Hg is desired:
