Let x = mass NaCl
Let y = mass KCl
=====================
x + y = 4
(AgCl/NaCl)x + (AgCl/KCl)y = 8.5904
where AgCl, NaCl, and KCl are the molar masses of each.
solve for x and y, then
percent NaCl = (x/4)*100 and
percent KCl = (y/4)*100
Post your work if you get stuck.
a mixture containing only sodium chloride and potassium chloride has a mass of 4 g. when this sample is dissolved in water and excess silver nitrate is added a white solid forms. after filreation and drying the solid silver chloride has the mass of 8.5904g. calculate the mass percent of each mixture component
