An experiment is conducted in order to determine the mass of
silver metal in an alloy. The alloy is dissolved in acid to
convert all the silver metal to silver ions, and those ions are
then precipitated by reaction with excess sodium chloride.
The precipitate is washed, dried and weighed, 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
What is the percent by mass of silver in the alloy?
a. 0.010000 %
b. 1.0787 %
c. 25.000 %
d. 100.00 %
