Quizplus · Accepted Answer

To find the number of cholesterol molecules, we can use Avogadro's number (6.022 × 10^23 molecules/mol) and the molar mass of cholesterol (386.65 g/mol). First, convert mg/dL to g/L for cholesterol: 178 mg/dL = 1.78 g/L. Then, calculate moles of cholesterol: 1.78 g / 386.65 g/mol = 0.0046 mol/L. Finally, find the number of molecules: 0.0046 mol × 6.022 × 10^23 molecules/mol = 2.77 × 10^21 molecules per deciliter.
