An experiment is conducted in to determine the mass of silver metal in an alloy. The alloy is dissolved in acid to convert all of the silver metal to silver ions, and those ions are then precipitated by the reaction with excess sodium chloride. The precipitate is washed, dried, and massed, and the following data are collected. Mass of silver alloy = 4.3148 g
Mass of filter paper = 0.50000 g
Mass of filter paper and dried precipitate = 1.9332 g

A. Identify the precipitate.
B. How many moles of the precipitate was used in the gravimetric analysis?
C. What is the % by mass of silver in the alloy?

How do I find A, B, and C? Show work if possible, please.
