076. Solving a chemistry problem

4. 3.036 g of technical KCl was dissolved in a 250.0 ml volumetric flask. 50.00 ml of 0.1045 M AgNO3 was added to 25.00 ml of solution. To titrate excess AgNO3, 20.68 ml of NH4SCN solution was consumed (T(NH4SCN/Ag) = 0.01166). Calculate the mass fraction of KCl in the sample.
