Thanks to you both. Unfortunately this is the kind of thing I have been experiencing... widely divergent results.PT

I am tincturing using a new device which requires a minimum of 2 cups of liquid but 3 is better so that is what I am using. The problem is: if I combine 8oz of 40% ethanol (80 proof) with 8oz of 76% ethanol (153 proof) and then add 8oz of distilled water, what percentage of ethanol will the final 3 cups be? I'm blushing to even have to write this but I have to get this project done and the final amount of ethanol needs to be known. I would really appreciate understanding how to get the final answer so I can just make adjustments going forward. Thanks for any help you can give. PT
