Percentage yield is calculated as the percentage of the  actual massmost useful producttheoretical massrelative formula mass that is actually made. Percentage yield might decrease because some of the reactants either  get used upare unstabledo not reactescape or react to form other products.

 Atom economyRate of reactionRelative atomic massReactant-to-product ratio is a way of comparing reactions to see which utilises the most  atomsenergyuncertaintyheat. It is better for this to be higher because it is more economic and  sustainableethicaleasiersafer.

When a substance is dissolved in a solvent, a  soluteliquidgassolution is formed. Its concentration can be calculated by dividing the number of moles of solute by its total  volumemassentropytype. This concentration has units of  dm3/cmdm3/molmol/dm3cm/mol. If more moles are dissolved, or a smaller volume of  solventsolidsolutegas is used, then the concentration will be higher. In a titration, one solution with a  highstablezeroknown concentration is reacted with a solution of unknown concentration to find its concentration.
