Question about biology / atoms

I got 18.75/.024 =781, not 700 moles. So that is off by slightly over 10%

Whoops, an arithmetic error then. Oh dear. Maybe a bit of "Covid brain".

When it happens to me, I simply claim old age.

Don't get me started.....Oops, too late!

We are very lucky to have you here. And a sense of humor too.

I wonder what it was when I was younger?

Personally, I don't remember that far back.

To add 2 cents about the production of wood.

That's a tattoo representation of a short piece of a cellulose molecule showing two of its glucose units. In between every two glucose monomers there is a 1,4 glucosidic bond represented by a red heart in the tat. In reality cellulose is generally much longer and may have many more glucose units though the one in the illustration only shows two. Separately a glucose molecule is chemically reactive and sweet. Combined they are no longer so reactive, don't rot as quickly, are difficult or impossible to digest.

The image may also be interpreted to represent starch if you prefer. Starch is different from cellulose only in real life, not in tats. Chemically starch and cellulose aren't the same and don't taste the same.

That is an interesting tattoo. Rather novel. At least it is not death's heads or scorpions.

There you go. Once again, age to the rescue.

I think in my case it would have been either simple carelessness or drunkenness.
