"From: Andy Wilde \n  \nI'm attempting to add data for stilpnomelane to the database. When trying to read the new file I get the message: reaction mass imbalance by -2. I have checked the reaction stoichiometry and formatting (see below) but cannot work out the error. The offending data (minus formatting): \nStilpnomelane type= \nformula= K.625Fe6AlSi8O21(OH)5.625:1.5H2O \nmole vol.= 375.390 cc mole wt.= 1071.8606 g \n6 species in reaction \n-15.6250 H+ 0.6250 K+ 6.0000 Fe++ \n8.0000 SiO2(aq) 1.0000 Al+++ 12.1250 H2O \n99.9999 99.9999 99.9999 99.9999 \n99.9999 99.9999 99.9999 99.9999 \n* gflag = 1 [reported delG0f used] \n* reference-state data source: 89Miy/Kle \n* delG0f = \n* delH0f = -2736865 cal/mol \n* S0PrTr = 215.7 cal/deg/mol \n"
