You want to clean a 500.-ml flask that has been used to store a 0.900M solution. Each time the flask is emptied, 1.00 ml of solution adheres to the walls, and thus remains in the flask. For each rinse cycle, you pour 9.00 ml of solvent into the flask (to make 10.00 ml total), swirl to mix uniformly, and then empty it. What is the minimum number of such rinses necessary to reduce the residual concentration of 0.000100 M or below?

Rewrite the text in past tense Use only third person, passive voice, e.g.: “Thirty grams of naphthalene was added 50 mL of m-xylene in a 250 mL round bottomed flask.” Experimental Procedure 1. Set up a simple distillation apparatus. 2. Add 16 g (16.7 mL) of cyclohexanol and 4 mL of concentrated sulfuric acid to the round bottom flask. Caution: Sulfuric acid is highly corrosive. Use caution and appropriate personal protective equipment! 3. Mix contents thoroughly and connect to distillation...
