Concentration of Phenol Solution (C_phenol): This is the concentration of phenol in the solution, typically measured in grams per liter (g/L) or milligrams per milliliter (mg/mL).
Volume of Phenol Solution (V_phenol): This is the volume of the phenol solution used in the reaction or process, typically measured in liters (L) or milliliters (mL).
Conversion Factor: If you have the mass of phenol in another form (e.g., moles of phenol), you'll need a conversion factor to convert it to milligrams.
