Part A: A solution of 100 ml of 500 ppm quinine solution was prepared this more concentrated solution was used to prepare a desired 5ppm quinine solution. How much solid quinine dihydrate (MW= 782.92 g/mol) will be needed to prepare the 500 ppm quinine solution, as well as the volume of 500 ppm quinine solution needed to make the 5ppm solution. Part B: If 61.1mg of quinine sulfate dehydrate was used what is the actual concentration in the solution ?
How would you prepare a 1/100 dilution (of a concentrated stock solution) in a final vol of 100 ml? 2.5 L? 87 ml? (ie how much diluent and how much of your concentrated stock)?
Solve the following 1) A solution is made by adding 24.8 mL of concentrated nitric acid (70.4 wt%, density 1.42 g/mL) to some water in a volumetric flask, and then adding water to the mark to make exactly 200 mL of solution. Calculate the concentration of this solution in molarity. 2) A 72.0 mL aliquot of a 1.50 M solution is diluted to a total volume of 288 mL. A 144 mL portion of that solution is diluted by adding...
