Furkat [3]

The concentration expressed in parts per million is 782 ppm.

<h3>What is Parts per million?</h3>

It is calculated by dividing the mass of the solution by the mass of a solute present in one million (10⁶) parts.

<h3>Calculation for units in ppm:</h3>

Given:

Mass of  blood alcohol =  80 mg/dL = 80 x 10^{5} g/mL

Density of blood plasma or Mass of blood plasma = 1.023 g/mL

Concentration in ppm = (Mass of alcohol/Mass of plasma) x 10^{6}

= (80 x 10^{5} g/mL/ 1.023 g/mL) x 10^{6}

= 782 ppm

Hence, the concentration expressed in parts per million is 782 ppm.
