Answer : The concentration expressed in parts per million is, 780.5 ppm
Explanation : Given,
Mass of alcohol = [tex]80mg/dL=80\times 10^{-5}g/mL[/tex]
Conversion used : [tex]1mg/dL=10^{-5}g/mL[/tex]
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.
[tex]\text{Concentration in ppm}=\frac{\text{Mass of alcohol}}{\text{Mass of plasma}}\times 10^6[/tex]
[tex]\text{Concentration in ppm}=\frac{80\times 10^{-5}g/mL}{1.025g/mL}\times 10^6=780.5ppm[/tex]
Thus, the concentration expressed in parts per million is, 780.5 ppm
The concentration expressed in parts per million is 780.5 ppm
Given:
Mass of alcohol = 80 mg/dL = [tex]80*10^{5}g/mL[/tex]
Density of plasma or Mass of plasma = 1.025 g/mL
Parts per million:
It is defined as the mass of a solute present in one million (10⁶) parts by the mass of the solution.
Calculation for units in ppm:
[tex]\text{Concentration in ppm}=\frac{\text{Mass of alcohol}}{\text{Mass of plasma}} *10^6\\\\\text{Concentration in ppm}=\frac{80*10^5g/mL}{1.025g/mL} *10^6=780.5ppm[/tex]
Thus, the concentration expressed in parts per million is 780.5 ppm.
