High-density lipoprotein (HDL) cholesterol is the “good” cholesterol because adequate levels reduce the risk of heart disease and stroke. HDL levels between 40. and 59 mg/dL are typical for a healthy individual. What is this range of HDL cholesterol in units of mol/L? The formula for cholesterol is C27H46O . Range of HDL cholesterol is between _____ and ______mol

Range of HDL cholesterol is between _____ and ______mol
dL stands for decilitre = (1/10) Litre
1 mg = (1/1000) g
Molar mass of cholesterol = 386.65 g/mol
for 40. mg/dL:
mg of cholesterol = 40. mg = (40. / 1000) g = 0.04 g
=> moles of cholesterol = 0.04 g / (386.65 g/mol) = 1.0345 * 10-4 mol
and volume = 1 dL = 0.1 L
=> concentration in molarity = 1.0345 * 10-4 mol / 0.1 L = 1.0345 * 10-3 mol/L
