62. It has been established that titration of 20 ml of AgNO3 solution requires 21.0 ml of NH4SCN solution. To a sample of 0.1173 g of NaCl, 30 ml of AgNO3 solution was added, and 3.20 ml of NH4SCN solution was used to titrate the excess silver nitrate solution. Calculate the molar concentration of AgNO3 and NH4SCN solutions, as well as Т(AgNO3/Cl).
