Question 4: Based on the procedure provided, how much acetic acid (in mL) should Ashe use when setting up the reaction at this new scale (to make 0.750 g of benzopinacolone)?

Ashe went into the lab to set up the following reaction: OH strong acid OH heat benzopinacol molar mass = 366.46 g/mol benzopinacolone molar mass = 348.45 g/mol They found a procedure ahead of time that says the following: "Combine 100 mg of benzopinacol and 1 mL of acetic acid in a test tube. Add a small crystal of iodine (the solution should brown), and warm the test tube gently. Follow the reaction by TLC. When it is complete (just a few minutes), chill the reaction mixture and filter the resulting crystals. You may have to add some cold ethanol to have enough liquid to filter. Wash the crystals with a little cold ethanol, then record a melting point and yield." (From Bell, Clark, and Taber)
