To the right is an image of a dilution that was performed. The volume above the top arrow indicates the volume that should be transferred to the next tube (i.e. Tube 1). The volume listed at the bottom-right of tube 1 indicates the volume of diluent that should be added to that tube. The stock concentration is 50μg/ml and you want to make a solution in tube 1 with a concentration of 0.4μg/ml and a total volume of 3ml. Stock ?ml Tube 1 ?ml a. How many milliliters of stock solution needs to be added to Tube 1? Round your answer to three decimal places (e.g. 0.111). b. How many milliliters of diluent needs to be added to Tube 1? Round your answer to three decimal places.
