This table gives the density ρ of mixtures of ethanol and water as a function of composition and temperature. The composition is specified in weight percent of ethanol, i.e., mass of ethanol per 100 g of solution. Values from the reference have been converted to true densities. Column definitions for the table are as follows.
Column heading | Definition |
Ethanol mass % | Concentration of ethanol, in mass % |
ρ(10 °C), ρ(20 °C), etc. | Density of ethanol, in g cm-3, at the concentration and temperature in °C as indicated by value within parentheses |
Mixture | Ethanol mass % | ρ(10 °C) /g cm-3 | ρ(15 °C) /g cm-3 | ρ(20 °C) /g cm-3 | ρ(25 °C) /g cm-3 | ρ(30 °C) /g cm-3 | ρ(35 °C) /g cm-3 | ρ(40 °C) /g cm-3 |
