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...

If the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of H2O at a given temperature, how many grams of NaCl can be dissolved in 250.0 mL of H2O? If the solubility of glucose (C6H12O6) is 120.3 g/100 mL of H2O at a given temperature, how many grams of C6H12O6 can be dissolved in 75.0 mL of H2O? Only 0.203 mL of C6H6 will dissolve in 100.000 mL of H2O. Assuming that the volumes are additive, find the volume/volume...
