A silver-copper alloy had a mass of 0.1264g. When the alloy was dissolved in nitric acid and the silver precipitated as silver chloride, the precipitate had a mass of 0.1375g. Calculate the percent of silver in the alloy.

So, how would you do this? Is it possible to use moles to find the answer?

  • Chemistry - ,

    Use the RAMs for silver and chlorine to find the mass (M_Ag) of silver in the precipitate by simple proportion.

    The percentage is then
    M_Ag x100%/0.1264
