Question

aquous urea solution is 3 molal hence mole fraction of urea is
?

Answer 1

3 molar aqueous solution means 3 moles of the solute in 1000g of water. If 18g of water is 1 mole , then 1000g of water will be 55.55 moles. So the mole fraction of a solute in a solvent is given by : number of moles of solute/ (number of moles of solute + number of moles of solvent).
