To write the percent concentration as a conversion factor and to use the percent concentration as a conversion factor. The percent concentration of a solution can be written in several different ways, including the mass percent, the volume percent, and the mass/volume percent. The percent concentration of a solution can be used as a conversion factor to determine information such as the amount of solute or amount of solution. For example, a 4% (m/m) solution means that there are 4...
