Calculate Avogadro's Number

Chemists use Avogadro's number in many calculations. This constant is the number of particles in a mole of a substance. It's an experimentally derived value that you can determine for yourself. One easy method uses electrochemistry to make the calculation. Current (electron flow) over time is measured in an electrochemical cell. The number of atoms in a weighed sample is related to the current to calculate Avogadro's number.
