A Vogadro
A Vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical physics. He was a physics professor but he also experimented in chemistry using mathematics to base most of his findings. Avogadro is well known for his hypothesis known as Avogadro's Law. His law states that at a given temperature, equal volumes of gas contain the same number of molecules equal to about 6.0221367 x 10 to the 23rd power.A Mole of a substance is the quantity of the substance that weights the same as its molecular mass. One mole of any substance is Equal to Avogadro's number. Therefore Avogadro's law can be stated in terms of moles, namely that equal volumes of gases at the same temperature and pressure contain the same
