Hi you all! I'm calculating the superficial tension of a dissolution made of increasing proportions of ethanol in water (20, 40, 60 and 80% v/v), and I need to know the densities of these dissolutions at 20ºC. Do you know where can I find them? I've only found some tables for water and ethanol. If these data aren't tabulated, can I find them out by interpolating if I know the densities of pure ethanol and water? Thanks a lot!

Check demo version of my CASC, it has density table for ethanol built in.
