Question

1. A patient has a “cholesterol count” of 214. Like many
blood-chemistry measurements,
this result is measured
in
units of milligrams per deciliter (mg d ^ -).
(a) Determine the molar concentration of cholesterol in
this patient’s blood, taking the molar mass of cholesterol
to be 386.64 g mol ^ -1.
(b) Estimate the molality of cholesterol in the patient’s blood.
(c) If 214 is a typical cholesterol reading among men in the
United States, determine the volume of such blood
required to furnish 8.10 g of cholesterol.
