Amedeo Avogadro was best known for creating Avogadro's Number (or Avogadro's Constant), discovered in 1820. We use this to calculate the results of chemical reactions. This discovery is very important because Avogadro's Number and the mole as a key part of understanding atomic structure. One mole of anything equals 6.022 x 10^23 particles.
Prior to creating Avogadro's Number, he discovered Avogadro's Law (otherwise known as Avogadro's Hypothesis or Avogadro's Principle) in the year 1811. This law states "equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties." The mathematical equation for this law is: V/n = k.
In this equation, the variable V stands for the volume of the gas, the variable n stands for the amount of substance of the gas, and the variable k stands for proportionality constant. Avogadro's Law is important because this equation applies to more complicated chemical formulas. Regardless of how hard you study new material, you would need to known Avogadro's Law because everything else builds off of it.
