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
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 
= (80 x
g/mL/ 1.023 g/mL) x 
= 782 ppm
Hence, the concentration expressed in parts per million is 782 ppm.
