Subject: converting anhydrous to mono...?

Hi all...

I'm making PO developer today and I need to convert anyhdrous Potassium Carbonate (what I have) to its mono (what I need) equivalent in weight.

Does anyone have the conversion factor and a reference...?

Much thanks...

Are you sure of this formula? It may have lost something in translation somewhere because it is _sodium_ carbonate that is often specified as being in the monohydrated form in photographic formulas. AFAIK there is no such thing as monohydrated potassium carbonate.
