Potassium carbonate is listed as K2CO3x1.5H2O FW165.23, for the anhydrous FW is 138.21
I do not see monohydrate. CHeck on this one more time. For the formula listed above you would need 138.21/165.23=0.8365 multiplied by the weight called for by the recipe.
make sure that your developer is on the acidic side. I keep some crystals of undissolved acid on the bottom. Watch the foaming as you add the carbonate.
