The molar mass of cholesterol = 386.654 g/mol = 387 g/mole

3.2 mg cholesterol x 1 g/1000 mg x 1 mole/387 g x 6.02x1023 molecules/mole = 5.0x1018  molecules.

The mass in grams of one molecule of cholesterol, C27H46O is 6.43×10⁻²² g

Avogadro's hypothesis

6.02×10²³ molecules = 1 mole of Cholesterol

But,

1 mole of Cholesterol = 387 g

Thus,

6.02×10²³ molecules = 387 g mole of Cholesterol

How to determine the mass of one molecule

6.02×10²³ molecules = 387 g mole of Cholesterol

1 molecule = 387 / 6.02×10²³

1 molecule = 6.43×10⁻²² g of Cholesterol

Thus, the mass of 1 molecule of cholesterol is 6.43×10⁻²² g
