A first-row transition metal sulfate (MSO4) does not liberate H2 gas upon reaction with dilute HCl. One mole of an aqueous solution of MSO4 is treated with an excess of aqueous KCN, forming a highly stable complex. When H2S gas is subsequently passed through this solution, no precipitate is formed. What is the amount of metal sulfide (MS) precipitated in this reaction?
