Question

Laws passed in some states define a drunk driver as one who drives with blood alcohol level of 0.10% by mass or higher. The level of alcohol can be determined by titrating blood plasma with potassium dichromate to the following equation: (equation shown in picture). Assuming that the only substance that reacts with dichromate import plasma is alcohol, is a person legally drunk if 38.94 mL of 0.0723 M potassium take him he is required to titrate a 50.0 g sample of blood plasma

The level of alcohol can be determined by titrating blood plasma with potassium dichromate according to the following equation:

\[ \text{16H}^+\text{(aq)} + \text{2Cr}_2\text{O}_7^{2-}\text{(aq)} + \text{C}_2\text{H}_5\text{OH}\text{(aq)} \rightarrow \text{4Cr}^{3+}\text{(aq)} + \text{2CO}_2\text{(g)} + \text{11H}_2\text{O}\text{(l)} \]

Assuming that the only substance that reacts with dichromate in blood plasma is alcohol, is a person legally drunk if 38.94 mL of 0.0723 M potassium dichromate is required to titrate a 50.0-g sample of blood plasma?
