30. A saturated solution of potassium chloride was
prepared at X °C. If 30 cm³ of this solution
required 22.5 cm³ of silver trioxonitrate (V) solution, containing 34g in 100cm3 solution, for complete precipitation, calculate the solubility of potassium chloride at X°C in (a) mol dm-3(b)g dm-3 (kcl=74.5,AgNO3
