You are working in a forensic lab and are given a blood sample from a suspected drunk driver. You are asked to determine the person's blood alcohol level. The legal limit is 0.08% by mass in most states. You use the following reaction in your determination, assuming only the ethanol (C2H5OH) in the blood sample will react with the dichromate: 16H+(aq)+2Cr2O72(aq)+C2H5OH(l)=4Cr3+(aq)+11H2O(l)+2CO2(g) If 14.6mL of 0.10MK2Cr2O7 are needed to react completely with 28g of blood, what is the blood alcohol level of the driver? \begin{tabular}{|l|} \hline 0.23% \\ \hline 0.03% \\ \hline 0.12% \\ \hline 0.34% \\ \hline 0.07% \\ \hline \end{tabular}
