1. What will be the concentration of iron in this new solution when the 5.00 ml of a solution containing 4.00 x 10-2M iron is placed in a 100.0 ml volumetric flask and filled to the mark with deionized water,
2. What percent of this compound is iron if a 1.50 g sample of an iron containing compound was dissolved in the 100.0 ml of solution. A 2.00 ml portion of this solution was placed in a 100 ml volumetric flask and diluted to the mark with deionized water. The iron concentration of this dilute solution was determined to be 1.112 x 10-3M.
