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
Reasonable values were made in the late 1800's from sedimentation equilibrium of colloidal particles. We all know that if we drop a lump of sugar into water it diffuses through the water, making it somewhat more sticky. 4 liters at STP(1 atmosphere and 223 Kelvin, 0 deg. Two years after his death, his colleague showed how they could use Avogadro's number to solve many of the problems in chemistry. Avogadro's number is most reliably determined by X-ray diffraction of crystals. Millikan's oil drop experiment in the 1900's gave even more accuracy and was cited in most chemistry text books 50 years ago. If it had not been for Avogadro and his findings there is no way that Chemistry in general would be where it is today. Cannizarro later used Avogadro's hypothesis to develop a set of atomic weights based on 116 of the weight of oxygen. the substance that weights the same as its molecular mass. 022045 x 10 to the 23rd power, However, in 1986 the number was redefined as about 6. Thanks to Avogadro and his number, scientists can measure out equal number of molecules by weighing out an equal number of moles. For gases this can be done by using 22.
