BRAINCAKECalculating Concentration
Once a mean titre has been found, the unknown concentration is calculated in three steps.
1. Moles of the known solution: amount = concentration × volume (dm3). This is usually the solution in the conical flask (measured with a pipette) or the standard solution in the burette.
2. Mole ratio: write the balanced equation and use it to find the amount of the other reactant.
