Part I. For each of the following four questions: calculate and describe how the requested solution would be made. Please show all of your calculations. In all cases the diluent or solvent will be water. Also, assume the smallest volume you can accurately pipette is 1ul. (CaClh: Molecular weight = 111.0 - NaCl: Molecular weight- 58.44) 1. From a 3M CaCh stock solution, you need to make 600 ml of 9 mM CaCl2. Indicate how you would make it. 2. You have a 20ul sample of DNA that you want to run in a gel. You are given 5X track dye; how much track dye do you add to your sample so that the track dye concentration in the sample is 1X? 3. You need to make 6 liters of 20% NaCl solution. Indicate how you would make it from powdered NaCl.

Part I. For each of the following four questions: calculate and describe how the requested
solution would be made. Please show all of your calculations. In all cases the diluent or
solvent will be water. Also, assume the smallest volume you can accurately pipette is 1ul.
(CaClh: Molecular weight = 111.0 - NaCl: Molecular weight= 58.44)
1. From a 3M CaCh stock solution, you need to make 600 ml of 9 mM CaClh. Indicate how
you would make it.
2. You have a 20ul sample of DNA that you want to run in a gel. You are given 5X track
dye; how much track dye do you add to your sample so that the track dye concentration in
the sample is 1X?
3. You need to make 6 liters of 20% NaCl solution. Indicate how you wvould make it firom
powdered NACI.
