National Mole Day commemorates Avogadro’s Number (6.02 x 10^23)

To thoroughly enjoy National Mole Day, one must first understand what a “Mole” in Chemistry is.

A “mole” is a basic measuring unit. It equals the atomic mass of a single molecule. It is measured in grams. This measure was discovered by Italian Amadeo Avogadro.

Chemistry teachers celebrate this day, by getting kids more interested in chemistry. They create special lessons and lab experiments around the theme of chemical measurements.

Why celebrate from 6:02 a.m. to 6:02 p.m? Look at the chemical formula for a mole. It starts with the number 6.02.
