A 0.9000-g of KIO3 is dissolved in 500-mL distilled water. A 50.0-mL aliquot portion was run down into an Erlenmeyer flask and 2-g of KI and 2-mL of 6M HCl were added to it. Directly after, the solution was titrated with a 24.80-mL Na2S2O3 solution to a faint yellow solution. Starch TS was added to the resulting solution and the titration with the Na2S2O3 solution continued wherein an additional 1.33-mL was required to bring the blue color of the solution to disappear completely.

The human microbiome is one of the major frontiers of current scientific investigation. Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?
