Question

What will be the molality of a solution having 18g of glucose dissolved in 500g of water?

Answer 1

Answer:

We know that the formula of molality is =Moles of solute/Mass of solution in(kg)

=here mole will be 18/180=0.1(molar mass of glucose is 180)

now, molality=0.1/0.5= 0.2 (mass of the solution must be in kg)
