One type of breathalyzer employs a fuel cell to measure the quantity of alcohol in the breath. When a suspect blows into the breathalyzer, ethyl alcohol is oxidized to acetic acid at the anode: Part A CH3 CH2 OH(g) + 4 OH (aq) → HC, H3 O2 (9) + 3 H2O(1) + 4e At the cathode, oxygen is reduced: O2 (g) + 2H2O(1) + 4e 4 OH (aq) Assuming a pressure of 1.0 atm and a temperature of 25 °C, what percent (by volum driver's breath is ethanol? The overall reaction is the oxidation of ethyl alcohol to acetic acid and water. When a suspected drunk driver blows 191 mL of his breath through this breathalyzer, the breathalyzer produces an average of 329 mA of current for Express your answer using two significant figures. 10 s. % Submit Request Answer Provide Feedback
