Mole day?
Indeed, mole day.
A mole is a unit of measure, like a cup or a quart, only... different. It’s more like a dozen, because it’s an exact number of items -- it’s 6.02 x 10^23 items. Which is a lot, unless you’re talking about atomic particles. The mole is used to measure quantities in chemistry, and its value was discovered by a guy named Avogadro. This number relates the atomic mass of an element to its mass in grams. So for example, oxygen has an atomic mass of 16, and 6.02 x 10^23 oxygen atoms weigh 16 grams. And when you’re doing calculations that span 3 or 4 or 5 pages, it’s a heck of a lot nicer to use moles for your quantities than to constantly write n.nn x 10^23.
Anyway my chem teacher in high school made a big deal about it whenever October 23rd came around. I would have thought that all chem teachers did, but I guess yours didn’t?
No, I never knew there was a holiday dedicated to remembrance of Avogadro and his #...interesting.
