-Born in Turin, Italy, on August 9th, 177 -Full name was Count Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto -Highly intelligent, when he was only 20, he was awarded a doctorate in canon law and began to practice as an ecclesiastical lawyer -Later grew out of studying law and decided to move into science at about age 16 -Was also a physics teacher for many years at Italian high schools and universities -Married Felicita Mazzé in 1818, they had six sons
equation: V1 / N 1 = V2 / N2
- "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules"
Avogadro's law states that…
Four tires stacked on top of each other have the same number of molecules. How do you know? They all have the same amount of air pumped into them so according to Avogadro they all have the same number of molecules.
Real World Examples
Two identical two pound basketballs lie next to each other. Since they have the same volume (or amount of gas inside), they therefore have the same number of molecules inside.
- First made the hypothesis in 1811 - His hypothesis was rejected by other scientists - The first scientist to realize that elements could exist in the form of molecules rather than as individual atoms - Avogadro published his first scientific paper to explain the electrical behavior of salt solutions in 1803 with his brother - Focused his early research on electricity - Avogrado’s calculator still exists today to show number of molecules in one mole of a particular substance
