You mix 55 mL of 1.00 M silver nitrate with 25 mL of 0.81 M sodium chloride. What mass of silver chloride should you form?

This is a limiting reagent problem.
Write and balance the equation.
NaCl + AgNO3 ==> AgCl + NaNO3

moles NaCl = M x L = ?
moles AgNO3 = M x L = ?

Use the coefficients in the balanced equation to convert mol NaCl to mol AgCl.
Do the same for AgNO3.
You get two answers; only one can be right. The correct one in limiting reagent problems is ALWAYS the smaller value and the reagent producing that number is the limiting reagent.

Then convert mol AgCl to grams. g = mols x molar mass.
