A blood cholesterol (C27H46O) level >240 mg per deciliter usually suggests medical intervention is needed.
If a patient has 247 mg/dL cholesterol level, calculate the concentration in terms of molarity (M).
I'm having a lot more trouble with this than I should be. A step-by-step answer would be greatly, greatly appreciated. Thanks.

I get 386.7 for the molar mass of cholesterol.
247 mg = 0.247 g
1 dL = 0.10 L
Calculate moles of cholesterol:
0.247 g x 1 mol / 386.7 g = 6.39 x 10^-4 mol
Calculate molarity:
6.39 x 10^-4 mol / 0.10 L = 6.39 x 10^-3 M
247 mg = 0.247 g
1 dL = 0.10 L
Calculate moles of cholesterol:
0.247 g x 1 mol / 386.7 g = 6.39 x 10^-4 mol
Calculate molarity:
6.39 x 10^-4 mol / 0.10 L = 6.39 x 10^-3 M
