# What's the density of a frozen ethanol or ethanol solutions?

How can we know what's the density of ice (water), but there's no data on how much is the density of frozen ethanol? (as far as I know)

• You've probably seen water ice quite a number of times. Frozen ethanol, on the other hand, requires going well beyond $-100^\circ\rm C$, which you probably don't do every day. That said, I believe the data is somewhere out there, only it's not that easy to come by. – Ivan Neretin Apr 17 '18 at 14:47
• The closest online source I found, celsius-process.com/pdf/ethanol.pdf , only goes to 4K above ethanol's m.p. It does seem that not all reference material is readily found online... yet. – DrMoishe Pippik Apr 17 '18 at 23:48
