Ok, so i took 50ml of EtOh/water mixture (47.2g EtOH/water mixture) and my distillate is 19mL
and 97.7g How do I find the % of EtOH by mass in the mixture?

Ethanol azeotrope is 96% http://en.wikipedia.org/wiki/Azeotrope
If your distillation is ideal, 96% will be collected first and the rest (if you distill longer) will be pure water
Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
