A pan contains 6,420 lbs of an aqueous solution at 104 °C. The said solution is 29.6% anhydrous sodium sulphate, the rest being H20. The solution is cooled without evaporation to 25 ° C at which Na 2 SO 4 bullet10H 2 O crystals form or separate . The remaining solution (mother liquor) is found to contain 16.1% anhydrous Na2SO4. ( a) What is the weight of the mother liquor ? (b) What is the % yield of the anhydrous solute ? () What is the weight composition of the mother liquor ?
