The level of alcohol can be determined by titrating blood plasma with potassium dichromate according to the unbalanced equation H+(aq)+ Cr2O72-(aq)+ C2H5OH(aq)àCr3+(aq)+ CO2(g)+ H2O Assuming that the only substance that reacts with dichromate in blood plasma is alcohol, is a person legally drunk if 38.94mL of 0.0723Mpotassium dichromate is required to titrate a 50.0-g sample of blood plasma?

Question
Laws passed in some countries define a drunk driver as one who drives with a blood
alcohol of 0.10% by mass or higher. The level of alcohol can be determined by
titrating blood plasma with potassium dichromate according to the unbalanced
equation
H+(aq)+ Cr2O72-(aq)+ C2H5OH(aq)àCr3+(aq)+ CO2(g)+ H2O
Assuming that the only substance that reacts with dichromate in blood plasma is
alcohol, is a person legally drunk if 38.94mL of 0.0723Mpotassium dichromate is
required to titrate a 50.0-g sample of blood plasma?
