23rd of October Celebrated as Mole Day to foster interest in chemistry

Post  bejoy on Fri Oct 21, 2016 12:56 am

Mole Day celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m. commemorates Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry.
What is a mole?
For a given molecule, one mole is a mass (in grams) whose number is equal to the molar mass of the molecule. For example, the water molecule has an molar mass of 18, therefore one mole of water weighs 18 grams. Similarly, a mole of neon has a molar mass of 20 grams. In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. This relationship was first discovered by Amadeo Avogadro (1776-1858) and he received credit for this after his death.
