Özet: In an illuminating experiment suitable for the first grade undergraduate and high school students, we tried to determine the Avogadro number considering accuracy and time. A voltage of 2.54 volt was applied to the circuit by immersing two zinc plate electrodes in ZnSO4.7H2O solution of 0,1M. When this voltage was applied, there was a current of 0,140 Amp in the circuit. The Avogadro number was evaluated, with an error of ± 0,07, by weighting the mass increase in the cathode at the end of a 1200-minute time period. Pedagogically, this activity interrelates the studies of electrochemistry and electrolysis in an efficient laboratory activity.
