for a lab I need to find the purity of a distillation sample (of ethanol) and calculate the % ethanol in the starting sample.
We started with 20mL of our solution then did fractional distillation. We were able to collect 9.6mL with a density of .8016. How do I calculate purity and how do I find the % of ethanol present in the original solution?
