A 250 mL solution of a 2.50 g sample containing silver was prepared. Silver content in the sample is determined by the Volhard Method. A 10.0 mL aliquot of the solution is titrated with a standard 0.101 M KSCN solution, requiring 7.0 mL to reach the red Fe(SCN)2+ end point. Calculate the percent mass of silver in the sample.
