Calculator for Combining Isopropyl Alcohol in water Solutions of Different Concentration at 20°C

This calculator calculates the amount and concentration of the solution that results from combining two solutions of known concentration. Volume or weight of Isopropyl Alcohol ((CH3)2CHOH) solution may be used. Just click on the weight or volume button to change to volume or weight units (Click here for illustration). To use water for diluting an Isopropyl Alcohol solution just input its concentration as zero percent (as in no Isopropyl Alcohol content). The calculator uses a table (see Examples) of concentration (% Isopropyl Alcohol by weight or volume) and its equivalent density. Interpolation is used to compute density values that are between the values in the table. The density is then used to compute volume or weight as needed. The Isopropyl Alcohol in water density-concentration table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Sixth Edition. This calculator includes the choice of expressing concentration in % Volume Isopropyl Alcohol. Click on the "Use Percent Volume Isopropyl Alcohol" button to switch to % Volume. Please be careful that the correct volume or weight units and the correct concentration expression (% Volume or % Weight) are used in your application. This calculator accounts for volume contraction that results when mixing Isopropyl alcohol and water.
