Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform calculations for solution mixtures (e.g., mixing two solutions) when working with molar or percent (%) solutions. See our Molar Solution Concentration Calculator for a definition of molarity and molar solutions. See also our Percent (%) Solutions Calculator for a definition of percent solutions. When working with % solutions, the concentration unit must be % for both the stock concentrated solution and final diluted solution. Additional solution mixtures calculators are also available and are suited to more specialized applications (see here).

The calculator below may be used when mixing two solutions, with molarity or percent (%) used for the concentration of the solutions. To use the calculator, enter appropriate values in all cells except the two cells you wish to calculate. For example, enter concentration and volume values for solution 1 and solution 2, and leave the concentration and volume for the solution mixture blank. Therefore, at least four cells must have values, and no more than two cells may be blank. The value of each blank cell will be calculated based on the other values entered. After a calculation is performed, the calculated cell will be highlighted and subsequent calculations will calculate the value of the highlighted cell (with no requirement to have a blank cell). However, a blank cell has priority over a highlighted cell.
