A sample of lead containing Ag as impurity welghing 0.8g was dissolved in a small quantity of nitric acid to produce an aqueous solution of Pb^(2+) and Ag^*. The volume of the solution was increased to 250 ml by addition of water. A pure silver electrode was immersed in the solution and the potential difference between this electrode and a standard hydrogen Belectrode is 0.50V at 25^@C. Calculate the percentage of silverin the sample.
