2.5 A solution of glucose in water is labelled as w/w, what would be the molality and mole fraction of each component in the solution? If the density of solution is then what shall be the molarity of the solution?
According to question, mass percentage means in 100 g of solution 10 g glucose is dissolved in 90 g water.
Molar mass of glucose (C6H12O6) =
So moles of glucose are :
Mole fraction :-
Molarity :- Volume of 100 g solution :
