AgNO3(aq) + NaCl(aq) ===> AgCl(s) + NaNO3(aq)

Atomic weights: Ag=108 Cl=35.5 AgCl=143.5

AgNO3 and NaCl react in a molar ratio 1:1. The molarities of the solutions are the same. But you have fewer mL of AgNO3 solution, so that will run out first--that is the limiting reagent.

21.00mLAgNO3 x 0.2000molAgNO3/1000mLAgNO3 x 1molAgCl/1molAgNO3 x 143.5gAgCl/1molAgCl = 0.6027g AgCl formed.
