chemical conversion

Anyone know how to convert sodium sulfide (not sulfite or sulfate) nonanhydrate to sodium sulfide anhydrate? I've got a pound of sodium sulfide nonanhydrate and want to use it, but formulas always call for sodium sulfide anhydrate.

Anyone know how to convert sodium sulfide ...
nonanhydrate to sodium sulfide anhydrate?

Sodium sulfide hydrate; Na2S-9H2O. Rounding a
very little, use 3 time as much. That's likely what
you've got, the 9 hydrate. It's 2/3 water. Dan
