Lapeer West Chemistry students celebrate "Mole Day" with handcrafted creations

Lapeer West students celebrate “Mole Day” with creations.

National Mole Day, which is held each October 23rd from 6:02 a.m. to 6:02 p.m. commemorates Amadeo Avogadro’s Number (6.02 x 10^23) which is a basic measuring unit in chemistry.

Mole Day was created to spark an interest in chemistry. Schools around the country celebrate in their own way, but at Lapeer West, Mrs. Kim Kent asks her students to create a mole creation as extra credit.

Students create the moles and a few had pretty interesting names, “Angelina Molie and Guacamolie.”

If you want the specifics:

“For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. An atom of neon has an atomic mass of 20, therefore one mole of neon weighs 20 grams. In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. Avogardro (1776-1858) discovered this relationship and received credit for this after he died.
