Famous scientist Avogadro has given this world the famous Avogadro Law to determine the molar masses and atomic masses
After overall study of a theory, a scientist published it but it was completed neglected during his life. Later on after learning the importance of that theory, scientists named a constant after him and paid tributes to him. The name of the scientist was Avogadro and the constant is Avogadro’s number.
The famous Avogadro Law is ‘equal volumes of all gases at the temperature and pressure contain the same number of molecules’. This law which is useful even today to determine the properties of various gases was given to this world in 1811.
Avogadro was born in Turin, Italy on 9th August, 1776 in the family of lawyers. As a student he was very active. He graduated at the age of 16 and gained his doctorate in Law related to Church. He was successful as a lawyer and was financially well settled, but he was not happy. He began private studies of mathematics, physics and chemistry. He researched in the field of electricity in the age of 24 years. Avogrado was appointed as the professor in Royal college. His theory is useful to determine not only molar masses, but also, indirectly, atomic masses. Avogrado also suggested that two molecules join together to form an atom. He also said that water is formed with one oxygen molecule and two molecules of hydrogen. His theories were neglected at his time. 4 years after his death, scientists could understand Avogadro’s law. And they have named the number which denotes a mole as ‘Avogadro’s number’ (20 zeroes after 6023). A crater on the moon was also named after him.
- The full name of Avogadro was Lorenzo Romano Amedeo Carlo Bernadette Avogadro di Quaregna e Cerreto.
- Avogadro number is so big that if we start counting one crore numbers per second it will take 200 crore years to finish the Avogadro’s number.
