The Faraday equation will tell you how much silver was released from the positive electrode. That is not exactly the same thing as ppm of Colloidal Silver. This equation only works well for CS up to a certain concentration and then, as you can see, there is a lot of silver wasted in unusable form. Even for low ppm CS, the equation is only indicates a theoretical maximum concentration, not the actual CS concentration.
