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: ch3ch2oh(g)+4oh−(aq)→hc2h3o2(g)+3h2 o(l)+4e−at the cathode, oxygen is reduced: o2(g)+2h2o(l)+4e−→4oh−(aq)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 323 ma of current for 10 s. assuming a pressure of 1.0 atm and a temperature of 25 ∘c, what percent (by volume) of the driver's breath is ethanol?
