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