A thin strip of iron with a mass of 15.5 g is placed into a solution containing 21g of copper (ll) sulfate and copper begins to form. After some time, the reaction stops because all the copper (ll) sulfate has reacted. The iron strip is found to have the mass of 8.5g. The mass of copper formed is found to be 8.6g. What's the mass of iron (ll) sulfate which has been formed in the reaction?
