∗∗ 100 g of P. mirifica contains an average of 15mg of Miroestrol:

1mg of crude P. mirifica = o.5 μg Ethyl Estradiol

1g of crude P. mirifica = (0.5)(1000 μg Ethyl Estradiol)

Therefore:

100 g of crude P. mirifia = (0.5)(1000)(100 μg Ethyl Estradiol)

100 g of crude P. mirifica = 50,000 μg Ethyl Estradiol
100 g of crude P. mirifica has 15 mg of Miroestrol.

15 mg of Miroestrol = 50,000 μg Ethyl Estradiol

1 mg of Miroestrol = (50,000)/(15 μg Ethyl Estradiol)

1 mg of Miroestrol = 3333.33 μg Ethyl Estradiol
