Problem

Equal volumes of 0.200 M

\text{AgNO}_3

(aq) and 0.200 M

\text{NaCl}

(aq) are combined, producing a precipitate exactly as depicted in a particulate diagram: every Ag

^{+}

ion pairs with a Cl

^{-}

ion to form solid AgCl, while all Na

^{+}

and NO

_3^{-}

ions remain in solution. If the total solution volume after mixing is 100.0 mL, approximately how many moles of NO

_3^{-}

ions remain in the solution? a)

0.020\,\text{mol}

0.010\,\text{mol}

0.000\,\text{mol}

0.005\,\text{mol}
