GG5 and Prog have "thickness" but I don't see how it fits. The kokugo definitions don't describe thickness, and it's not used in any of the JE example sentences.

The "chem" is OK. It need not be exclusive. I see Daijirin breaks it into two senses, and has 化 and 数 tags.

Uh this one is really hard.

Even though couple of refs say "density" it should not be confused with 密度(density). As usual, I'm hesitant to remove the gloss even though it seems misleading to me.

Also, is it OK to slap the [chem] tag on [1]? It's not exclusively a technical term, but it is the correct term for molar/mass concentration.
