Re: Does ANyone KNow?
You're looking for a hydrometer, specifically one for measuring
ethanol - water mixtures.
But as long as you measure correctly, then why worry? By "measuring
correctly" I mean separately. Water and ethanol have a curious
property: when mixed, they make up less volume than their separate
volumes added. I.e. 50 mL water + 50 mL ethanol make *less* than 100
mL water-ethanol mixture. I've forgotten the physical chemistry, but
I'll bet someone on the list knows ...
