When performing a gram stain, it is necessary to remove crystal violet stain from any gram negative bacteria on the slide. Microbiologists use a decolorizing solution to accomplish this. A common recipe is equal parts 95% ethanol and acetone. How many mL of water would you need to add if you have 100% ethanol and want to end up with 300 mL of decolorizer? Report your answer to 2 decimal places and perform all calculations in a singlet step using Excel to avoid accruing rounding error.
