Cortisone acetate has 4 chiral centers, therefore it has 2^4 = 16 possible stereoisomers. However, since it is a racemic mixture of enantiomers, there are only half as many unique enantiomeric pairs, which is 16/2 = 8. Each pair consists of two enantiomers (mirror images), so the total number of enantiomers is 8 x 2 = 16.
