A person is considered legally intoxicated with a blood alcohol level of 80 mg/dL. Assuming that blood plasma has a density of 1.025 g/mL, what is this concentration expressed in parts per million?

Answer : The concentration expressed in parts per million is, 780.5 ppm

Explanation : Given,

Mass of alcohol =

Conversion used :

Mas of plasma = 1.025 g/mL

Parts per million (ppm) : It is defined as the mass of a solute present in one million (10⁶) parts by the mass of the solution.

Now we have to calculate the concentration in ppm.

Thus, the concentration expressed in parts per million is, 780.5 ppm

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
