$\left[{\mathrm{Ba}}^{2+}\right]=0.5\mathrm{mol}{\mathrm{L}}^{-1}$ $$\begin{array}{rl}& \left[{\mathrm{SO}}_4^{2-}\right]=1\mathrm{mol}{\mathrm{L}}^{-1}\\ & {\mathrm{Ba}}_{(aq)}^{2+}+{\mathrm{SO}}_{4(aq)}^{2-}\rightleftharpoons {\mathrm{BaSO}}_{4(s)}\end{array}$$ $0.5\mathrm{mol}$ of ${\mathrm{Ba}}^{2+}$ would react with $0.5\mathrm{mol}$ of ${\mathrm{SO}}_4^{2-}$ ions to form $0.5\mathrm{mol}$ of ${\mathrm{BaSO}}_4$.
