16. Solving a chemistry problem
31. The dependence of the specific electrical conductivity of potassium nitrate solutions on concentration is expressed as follows:
Cn, mol/l 0.01 0.02 0.03 0.04 0.05 0.06
æ, Sm•m–1 0.1358 0.2649 0.3901 0.5123 0.6321 0.7498
How many ml of a KNO3 solution, whose electrical resistivity is 1.62 Ohm•m, should be taken to prepare 250 ml of 0.005 N. solution?
