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.

Q3: 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 98% ethanol and want to end up with 460 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.
A student pipetted 10 mL of a sample solution into a 250 mL volumetric flask and diluted it to the mark with distilled water. The student then, pipetted 10 mL of this new solution into a 50.00 mL volumetric flask and diluted it to the mark with water. What is the dilution factor of the final solution? 25X 100X 125X 5X 50X
A chemistry student weighs out 0.152g of phosphoric acid H3PO4 , a triprotic acid, into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.2000M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits.
A chemist must prepare 300.mL of 2.00M aqueous silver perchlorate AgClO4 working solution. He'll do this by pouring out some 5.62molL aqueous silver perchlorate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the silver perchlorate stock solution that the chemist should pour out. Round your answer to 3 significant digits.
A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 60% salt and Solution B is 85% salt. She wants to obtain 80 ounces of a mixture that is 70% salt. How many ounces of each solution should she use? Note that the ALEKS graphing calculator can be used to make computations easier.
The composition of a mixture of potassium chlorate and potassium chloride is to be determined. A 8.96 gram sample of the mixture is heated until the creation of oxygen gas stops. If the sample mass after heating is 7.89 grams, what is the percent by mass of potassium chlorate in the mixture? Report your answer with 3 significant figures.
A chemistry student weighs out 0.160g of sulfurous acid H2SO3, a diprotic acid, into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1600M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits.
