Can someone tell me what is "subcarbonas ammoniae or volatile salt of sal ammoniac"? aka "sal volatile" salis ammoniaci, Formula? Thank you.

This can be ammonium bicarbonate, NH4HCO3.
Most often, however, it refers to ammonium carbonate, (NH4)2CO3.
The latter is much more volatile than the first one and if you keep a small amount of ammonium carbonate in contact with air, it slowly disappears.
