How to calculate % yield of an azeotropic mixture??

I did a distillation experiment on a mixture of 1-propanol and water (50%v/v). I know the % composition of the azeotrope by weight: which is 71.7% propanol and 28.3% water. I distilled 30mL of the azeotrope and 19mL of water. How do I calculate the theoretical yield for the azeotrope and water?
