What mass of "lead chloride"lead chloride would result if a 21.5*mL21.5⋅mL volume of "lead nitrate"lead nitrate at 0.0806*mol*L^-10.0806⋅mol⋅L−1 concentration were mixed with a 18.00*mL18.00⋅mL volume of "potassium chloride"potassium chloride at 0.683*mol*L^-10.683⋅mol⋅L−1 concentration?

Explanation:
We need (i) a stoichiometric equation.....
Lead chloride is one of the few water-insoluble halides. It crashes out of water solution with alacrity.
And (ii) we need equivalent quantities of each reagent......
And thus (clearly) chloride anion is the limiting reagent. Stoichiometry predicts that half an equiv of plumbous chloride will precipitate.
It is unusual that the chloride ion is in stoichiometric deficiency in that you would think we want to salt out the lead content......
