If we need 80mL of 0.3M NaCI, it is harder to calculate. For any
dilution we can use the formula C,V1 = C2V2. Using this formula,
how many mL of 5M NaCl do you need to make the specificed
solution?
Using the concentrated bacterial sample above, how many mL of
bacterial culture and how many mL of culture media would you
need to make 25 mL of bacteria at 1x105 ell/mL?
How many mL of the original culture would contain 1x106 cells?
