A particular oral contraceptive contains 0.041 mg of ethinyl estradiol in each pill. The formula of this compound is C20H24O2. How many moles of ethinyl estradiol are there in one pill?

I need help in approaching this

  • Chemistry -

    (1) Convert 0.041 milligrams to grams (divide by 1000)
    (2) Find the formula mass of C20H24O2 to get the grams per mole.
    (3) Divide the answer to step #1 by the grams/mole

  • Chemistry -

    The other two parts are:
    1) How many carbon atoms are there in one of these pills (due to the presence of ethinyl estradiol)?

    2What mass of carbon is this? (Enter the answer in grams.)
