Potassium trioxochlorate (V)has a solubility of 1.5 mol dm -3 at 45 oC.On cooling this solution to a temperature of 20 oC, the solubility was found to be 0.5 mol dm -3. What mass of KCIO 3 was crystalized out?
[K = 39, Cl = 35.5 O =16]

Mole=1.5-0.5 = 1

RMM =39+35.5+(16*3)=122.5

Mole=mass/RMM

Mass=mole*Rmm

=1*122.5=122.5

39+35.5+16×3

74.5+48=122.50
