Density and Concentration Calculator for Mixtures of Ethanol and Water at 20°C

This is a table of density (kg/L) and the corresponding concentration (Weight% or Volume%) of Ethanol (C₂H₅OH) in water at a temperature of 20°C. The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Seventh Edition. The calculator does automatic interpolation calculation for density or concentration values that are between those in the table. In effect, any value within the range of the table can be calculated. Input any one value of Density, Concentration in % Volume, or Concentration in % Weight of Ethanol in water to calculate for the other two values. Please input only one value and leave the values to be calculated blank. In practice, density is determined by means of a hydrometer or by weighing a known volume of a solution. This updated calculator now includes Volume% Ethanol as a paramenter so it can now be calculated for or given as a value. Here is the link for those who prefer the old calculator.
