Question

One patient had a cholesterol concentration of 0.187M in the blood plasma if the molar mass of cholesterol is 387g/dl to 270 mg/dl will that concentration be within the normal parameters?

Answer 1

The problem statement has some errors. Nevertheless I will post an answer which will explain the concept.

Conc. of cholesterol = 0.187 M = 0.187 moles/L

Molar mass of cholesterol = 387 g

So,

Conc. in g/L = Conc. in Molarity*Molar mass = 0.187*387 = 72.37 g/L = 7.237 g/dl = 7237 mg/dl

Since the borderline for normal cholesterol range is about 270 mg/dL, but the conc in this case is way too much (7237 mg/dL), so the concentration is not within normal parameters.
