What is the molecular mass of cholesterol if 0.5731 mol weighs 221.6g?

I need to show my work using conversion factors.

  • chemistry -

    moles = grams/molar mass.
    0.5731 = 221.6/molar mass
    molar mass = 221.6/0.5731 = 386.67.

    By conversion factor.
    molar mass = 221.6g x (1 mol/0.5831g) = ??
