webmaster Posted November 3, 2004 Share Posted November 3, 2004 From: Andy Wilde I'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): Stilpnomelane type= formula= K.625Fe6AlSi8O21(OH)5.625:1.5H2O mole vol.= 375.390 cc mole wt.= 1071.8606 g 6 species in reaction -15.6250 H+ 0.6250 K+ 6.0000 Fe++ 8.0000 SiO2(aq) 1.0000 Al+++ 12.1250 H2O 99.9999 99.9999 99.9999 99.9999 99.9999 99.9999 99.9999 99.9999 * gflag = 1 [reported delG0f used] * reference-state data source: 89Miy/Kle * delG0f = * delH0f = -2736865 cal/mol * S0PrTr = 215.7 cal/deg/mol Quote Link to comment Share on other sites More sharing options...
webmaster Posted November 4, 2004 Author Share Posted November 4, 2004 From: Craig Bethke Maybe my calculator has a bad chip, but when I add up the mole weight for this compound, I get 1070.484 g/mol, not 1071.8606. Quote Link to comment Share on other sites More sharing options...
