A sample of water from a large swimming pool has a resistance of 9000 ohm at 250C when placed in a certain conductance cell. When filled with 0.02 M KCl solution, the cell has a resistance of 85 ohm at 250C. 585 gm of NaCl were dissolved in the pool, which was thoroughly stirred. A sample of this solution gave a resistance of 7500 ohm. Given NaCl 130 ohm1cm2mol1 and KCl at 0.02M 140 ohm1cm2mol1 56. Cell constant of the conductance cell is 57. Specific conductance due to NaCl is
