YouTube Upload – Chemistry / Atomic Weights Set 2


Good evening All,

I’ve uploaded a second set of problems relating to the work of Avogadro and atomic and molecular weights. You can find the set here.

Lorenzo Romano Amedeo Carlo Avogadro’s most important contribution was the idea that equal volumes of gases under the same temperature and pressure contained equal numbers of molecules. He was one of the first to differentiate between atoms and molecules, stating that gaseds are made of molecules, and those molecules are made of atoms (his elmentary molecule). His contributions, and similar ones by other scientists went basically unnoticed for about 100 years. His efforts were finally recognized though, and today he is considered to be the founder of the atomic-molecular theory.

As always email me should you have any questions or would like to see a partucular type of problem done.

See you Friday at the whiteboard with more Physics problems.
