The percent concentration of a solution is a ratio of the amounts of dissolved solute and solution, expressed as a percentage. The percent concentration of a solution can be written generally as % concentration = amount of solute amount of solution ×100% Depending on the situation, a percent concentration might be calculated for mass/mass, volume/volume, or mass/volume.
