A persons blood alcohol c2h5oh level can be found by, Ask an Expert

Academics

A person's blood alcohol (C2H5OH) level can be found by titrating a sample of blood plasma with potassium dichromate solution. The equation

16 H+ (aq) + 2 Cr2O7^2- (aq) + C2H5OH (aq) ---> 4Cr3+ (aq) + 2CO2 (g) + 11H2O (l)

If 35.46mL of .05961 M Cr2O7^2- is needed to titrate 28.00g of plasma, explain what is the mass percent of alcohol in the blood?
