Chemistry Equations (C1 -> C7) 0.0 / 5 ? ChemistryCalculations, moles and yieldEquationsGCSEAQA Created by: Charlotte HerondaleCreated on: 20-12-18 11:05 Number of Neutrons in Atom = Mass number - Atomic number 1 of 15 Relative Formula Mass (Mr) = Atomic Mass + Atomic Mass... 2 of 15 Mol = Mass / Mr 3 of 15 Mass (g) = Mol x Mr 4 of 15 Mr = Mass / Mol 5 of 15 Yield (%) = (Actual Yield / Theoretical Yield) x 100 6 of 15 Atom Economy (%) = (Mr of Desired Product / Mr of All Reactants) x 100 7 of 15 Concentration (g/dm3) = Solute Mass (g) / Solution Volume (g) OR Mol / Vol (dm3) 8 of 15 Mol (concentration) = Conc (mol/dm3) x Vol (dm3) 9 of 15 Vol (concentration) (dm3) = Mol / Conc (mol/dm3) 10 of 15 Gas Mol = Volume (dm3) / 24 11 of 15 Gas Vol (dm3) = Mol x 24 12 of 15 Gas Conc = 24mol/dm3 13 of 15 Increase of H+ Ion Concentration by Factor of 10 = Decrease of pH by 1 unit 14 of 15 Energy Transferred in Reactions (kJ/mol) = (Reactant Bond Energy + Reactant Bond Energy...) - (Product Bond Energy + Product Bond Energy...) 15 of 15
