- After a certain amount is taken from a sample containing 5% (w/w) NaCl, it is dissolved by the addition of water and analyzed according to the Volhard method. Into this solution, 50 ml of 0.1M AGNO; solution is added. Then, the unreacted AgNO, is back titrated with 0.2 M NH,SCN solution. If 7.9 ml of NH SCN solution was consumed in this titration, what is the amount that was taken from the sample? (NaCl:58.5 g/mol)
