It is straightforward.
a) calculate themass of the chloride in the silver chloride.
b) calculate the chloride in .887g naCl
subtrace b from a
the remainder is cl in KCl. knowing that mass of chlorde ion, compute the mass of KCl.
a bit of math, but not rocket science here.
A 0.8870-g mixture of sodium chloride and potassium chloride is dissolved in water and silver nitrate is added. The AgCl that precipitates has a mass of 1.913 g. Calculate the percent by mass of potassium in the initial mixture。
