a silver coin has a mass of 2.50g and is analysed for silver by dissolving in dilute nitric acid, and precipitating silver as solid AgCl and weighing this. if the percipitate weighs 2.99g what percentage of silver is in the coin?

  • Chemistry -

    If you have AgCl, what percentage of that mass is Ag? I estimate it is about 80 percent, work it out accurately.
    what is the mass of silver? Ans: .80(about)*2.99

    so what is the percent of silver in the coin? masssilver/mass of coin
