70. Solving a chemistry problem
Determine the mass of a sample of potassium chloride dissolved in water in a volumetric flask with a volume of 500.00 cm3, if 50.00 cm3 of 0.10 mol / dm3 of silver nitrate solution with Kp = 0.9870 were added to 25.00 cm3 of this solution. The silver nitrate residue was titrated with 23.60 cm3 of an ammonium thiocyanate solution with a titer of 0.007580 g/cm3
