A solution gas been prepared by dissolving 5 g of urea in 95 g of water. What is the mass percent of urea in the solution ?

An aqueous solution is made by dissolving glucose (C_(6)H_(12)O_(6)) and urea (NH_(2)CONH_(2)) in water. The mole ratio of glucose and water is 1 : 10. If the masses of glucose and urea are in 3:1 ratio, the mole fraction of glucose in the solution is :
