Calculate a sample for the preparation of 1000 ml of a titrated solution of ammonium thiocyanate with a concentration of 0.1 mol/L. How many ml of a solution of silver nitrate with a concentration of 0.1 mol / l with K = 1.0000 must be taken to set the correction factor for the molarity (K) of an ammonium thiocyanate solution so that 20.00 ml of titrant is used for titration? Mm. ammonium thiocyanate 76.12 g/mol. Mm. silver nitrate 169.87 g/mol
