1 a persons blood alcohol c2h5oh level can be determined by, Ask an Expert

Academics

1) 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 Cr2O72-(aq) + C2H5OH(aq) 4 Cr3+(aq) + 2 CO2(g) + 11 H2O(l)

If 39.02 mL of 0.05919 M Cr2O72- is required to titrate 27.62 g plasma, what is the mass percent of alcohol in the blood?

2) How many total moles of ions are released when (6.004 1021 formula units of NiCl2 dissolves completely in water?
