What is the molar mass of cholesterol (C27H460), a fat found in your blood and

cell membranes?

260.12 g/mol

386.76 g/mol

130.38 g/mol

29.12 g/mol

386.66 g/mol

Explanation:

To calculate the molar mass of a molecule, you add up the molar masses of its atoms.

Thus, for cholesterol. we get

27C = 27 * 12.011 = 324.297 g

46H = 46 * 1.008 = 46.368

1O = 1 * 15.999 = 15.999

TOTAL = 386.655 g

To two decimal places, the molar mass of cholesterol is 386.66 g/mol
