the solubility of Kl is 50g in 100g of H2O at 20 celcius, if 110g of Kl are added to 220g of H2O, is the soultion saturated or unsaturated?
and what is the %m/m of the solution?

Solubility is 50 g KI/100 g H2O; how much water will it take to dissolve 110 g KI? That will be 100 g H2O x (110mL/50mL) = 220 g H2O. The solution is saturated since that is what it will hold but no more.
110 g KI/220 g H2O is
110 g KI/(220gH2O + 110g KI) = 110/(330g soln).
% w/w = (110 g KI/330 g soln) * 100 = ??
