(Equilibrium constants for the reaction in water and benzene are $K_{Water}$ $K_{Benzene}$)

$Fe ^{2+}( aq )+ S ^{2-}( aq ) \rightleftharpoons FeS ( s )$
When equal volumes of $0.06 M Fe ^{2+}( aq )$ and $0.2 M S ^{2-}( aq )$ solutions are mixed, the equilibrium concentration of $Fe ^{2+}$ (aq) is found to be $Y \times 10^{-17} M$. The value of $Y$ is. . . . .
