[meteorite-list] Etching Compounds

Hola,
Concentrated nitric acid is about 16 molar (70%).

You don't want any water you can avoid.  It is then diluted (by pouring acid into alcohol) down to "1 molar" (16:1 vol/vol), but in quotes because that should be with anhydrous, or 95% minimum ethyl alcohol....I usually consider "molar" as in water, hence the important clarification.
