- The stock erythrosine B solution is 8.5 × 10-5 M. Calculate the volume of this solution that you must pipet into a 50-mL volumetric flask, which, when diluted to mark with deionized water, will give a final concentration of 1.7 × 10-5 M. Show your calculation setup.calculate for percent recovery, and explain what does 50:50 mixture means? since total mass is 0.102 g, does it means 0.051 for ferrocene, and another 0.051 for acetyferrocene. I feel confused.The same physical property that helps drive the reaction to completion can also stall out the reaction before it starts. What do we do in the procedure that helps minimize this concern?
