Blood alcohol concentration, or BAC, is a measure of the percentage of alcohol in whole blood. In the US, a BAC of 0.08 percent or above is considered legally intoxicated; this number translates to roughly 80 milligrams (mg) of alcohol in 1 deciliter of whole blood (80 mg/dL). A standard drink contains roughly 14 grams (g) of alcohol, and the average man and woman have 5 and 4 liters (L) (50 and 40 dL) of whole blood, respectively. Several factors can influence BAC (i.e. Gender, age, body mass, genetics, hydration and food, drinking frequency), but BAC can be estimated using the Widmark Formula: BAC = [alcohol consumed in grams / (body weight in grams * r)] x 100 Here, r is a constant related to the distribution of water in the body and differs by gender; 0.55 is used for females and 0.68 is used for males. As mentioned earlier, the length of time over which the alcohol is consumed also needs to be taken into account. Question: Based on the information above, calculate Michael's BAC level. Type answer as a number followed by ____%. Would Michael be considered legally intoxicated based on this BAC - yes or no? And the yellow color is caused by the buildup of which molecule that is usually metabolized by the liver?

Here in the state, an individual is legally intoxicated if that person's blood alcohol content (BAC) is 0.08 % (w/v) or higher. How many milligrams (mg) of alcohol are contained in 5.0L of blood with this level? ( 1 mg = 0.001 g, 1 mL = 0.001 L).

The legal blood alcohol content (BAC) in California is 0.08% by mass. Blood samples are titrated with K2Cr2O7 to determine the alcohol content according to the following reaction: 6 CH3CH2OH + 4 K2Cr2O7 + 16 H2SO4 → 6 CH3COOH + 4 Cr2(SO4)3 + 4 K2SO4 + 22 H2O In this reaction, the chromium is reduced, from Cr6+ to Cr3+, causing a color change in the solution, signaling the end point. Determine the mass percent ethanol in a 50.0 g blood sample, if the sample required 25.6 mL of 0.05 M K2Cr2O7 to react completely with all the ethanol. Was this person intoxicated above the legal limit?
