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?
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
