$1.0\times {10}^{-3}\mathrm{mol}$ of ${\mathrm{Ag}}^{+}$ and $1.0\times {10}^{-3}\mathrm{mol}$ of ${\mathrm{CrO}}_4^{2-}$ react together to form solid ${\mathrm{Ag}}_2{\mathrm{CrO}}_4$. What is the amount of ${\mathrm{Ag}}_2{\mathrm{CrO}}_4$. formed?

(Molecular weight of $\left.{\mathrm{CrO}}_4=332\right)$
