Aqueous mixture was made by dissolving $1.0\,\text{mol}$ of $\text{AgNO}_3$ and $1.0\,\text{mol}$ of $\text{FeSO}_4$ in $1.00\,\text{dm}^3$ of water. After equilibrium had been reached, the mixture contained $0.44\,\text{mol}$ of $\text{Ag}^+(\text{aq})$. $\text{Ag}^+(\text{aq}) + \text{Fe}^{2+}(\text{aq}) \rightleftharpoons \text{Ag}(\text{s}) + \text{Fe}^{3+}(\text{aq})$ What is the numerical value of $K_c$?
