2molar solution has density 2g/ml calculate in terms of mole fraction.

1.	2molar solution has density 2g/ml calculate in terms of mole fraction.
Answer» 2molar means 2 mole of solute in 1litre of solution(usually solvent is water) . Since the value of solute is negligible in 1 litre of water. Now density of solution is 2g/ml. So the mass of solution in 1 litre is equal to 2000g . the molar mass of water is 18g/mol. So no. of moles of solution is equal to 2000/18 . So find the mole fraction using this information.
