Solve the set of problems shown below with reference to the following information about ethanol. Ethanol (C2H5OH): molar mass = 46.069 g/mol. Density of absolute (100 % v/v) ethanol = 0.7893 g/mL. The legal limit for a driver’s blood alcohol in Australia is 50 mg of ethanol per 100 mL of blood (referred to as a blood alcohol content (BAC) of 0.05 %). What is the molarity of ethanol (in blood) in a person at this legal limit?

Question

Solve the set of problems shown below with reference to the following information about ethanol.

  • Ethanol (C2H5OH): molar mass = 46.069 g/mol.
  • Density of absolute (100 % v/v) ethanol = 0.7893 g/mL.

The legal limit for a driver’s blood alcohol in Australia is 50 mg of ethanol per 100 mL of blood (referred to as a blood alcohol content (BAC) of 0.05 %).

           

            What is the molarity of ethanol (in blood) in a person at this legal limit?
