Key Formulas for Amount of Substance (n)
There are primary ways to calculate the amount of substance (moles), depending on the information you have:
- From Mass and Molar Mass:
n = m / Mwhere:- n = Amount of substance (moles)
- m = Mass of the substance (grams)
- M = Molar mass of the substance (grams/mole)
- From Concentration and Volume:
n = C × Vwhere:- n = Amount of substance (moles)
- C = Concentration of the solution (moles/Liter or Molarity)
- V = Volume of the solution (Liters)
