This is a table of density (kg/L) and the corresponding concentration (% weight) of Ethanol (C2H5OH)
in water at a temperature of 20 degrees centigrade. 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. Just input the density of the solution and the calculator will compute
for the corresponding concentration. Or input the concentration to get the corresponding density.
Please input only one value and leave the value to be calculated blank. In practice, density is
determined by means of a hydrometer or by weighing a known volume of a solution.
