Your protocol calls for a 0.15MM NaCl solution. How would you dilute your 3M NaCl solution to 0.15M as your protocol calls for? You can determine the overall dilution factor needed by dividing the final concentration (0.15mM NaCl), by the starting concentration (3M NaCI) (0.00015M/3M = 1/20,000). !! 11. If you want to do this in 3 steps, what woul be three individual dilution factors you could use? Use as your total volume 500 pl. 12. What would be the concentration (in Molarity) for each of your three dilutions, individually? (Note: remember you started with 3M NaCI)
