Homework Help: chemistry

Posted by Komal on Thursday, November 6, 2008 at 9:36pm.

Laws passed in some states define a drunk driver as one who drives with a blood alcohol level of 0.08% by mass or higher. the level of alocohol can be determinded byt titrating blood plasma with pottasium dichromate according to the unbalanced redox reaction.

igot the balanced equation--

C2O72- + 14 H + 3H2O + C2H5OH ---> 2cr3+ + 7H2O + 2CO2 + 6H

-- assuming that the only substance that reacts with the dichromate in blood plasma is alcohol, is a person legally drunk if 38.94 ML of 0.0723M potassium dichromate is required to titrate 50.0 g sample of blood plasma?

HELP ME PLZ.. THIS IS FOR A GRADE.. THANKYOU! :)
