Blood alcohol $(C_2H_5OH)$ levels can be determined by the following titration:

$$16 H^++ 2 Cr_2O_7 \ ^{2-} + C_2H_5OH → 4 Cr^{3+}+ 2 CO_2+ 11 H_2O$$

The endpoint is reached when the orange (dichromate ion) solution turns green (chromium ion).

How many electrons are transferred if a mole of alcohol is titrated to its endpoint?


$1.8 \times 10^{24}$


$3.6 \times 10^{24}$


$7.2 \times 10^{24}$


$9.6 \times 10^{24}$
