Define molarity.

Define molarity.

Calculate a) molality b) molarity and c) mole fraction of KI if the density of 20% (mass / mass) aqueous KI is 1.202" g mL"^(-1) . As density and % by mass is given, so find the mass of solute and solvent (as x % solution contains x g solute in (100 - x) g solvent). Find volume of the solution, by using,, Volume =("Mass")/("Density") Recall the formulae of molality, molarity and mole fraction, to calculate them. Molality =("Mass of solute/ molar mass of solute")/("Mass of solventin kg")
