A person’s blood alcohol (C2H5OH) level can be determined by titrating a sample of blood plasma with a potassium dichromate solution. The balanced equation is
16 H+ (aq) + 2 Cr2O7 2−(aq) + C2H5OH(aq) ⟶ 4 Cr3+(aq) + 2 CO2(g) + 11 H2O(l)
If 35.46 mL of 0.05961 M Cr2O7 2− is required to titrate 28.00 g of plasma, what is the mass percent of alcohol in the blood?
