Percentage yield is calculated as the percentage of the  relative formula masstheoretical massactual masssolid product(s) that is actually made. Percentage yield might decrease because some of the reactants either  get used upescapelose massdo not react or react to form other products.

 Rate of reactionAtom economyRelative atomic massAvogadro's rule is a way of comparing reactions to see which utilises the most  surface areaenergyatomsuncertainty. It is better for this to be higher because it is more economic and  safersustainableethicalenergy-intensive.

When a substance is dissolved in a solvent, a  solutionsolidgassolute is formed. Its concentration can be calculated by dividing the number of moles of solute by its total  typevolumemasspressure. This concentration has units of  mol/dm3dm3/moldm3/cmmol/dm. If more moles are dissolved, or a smaller volume of  soluteproductsolidsolvent is used, then the concentration will be higher. In a titration, one solution with a  lowhighstableknown concentration is reacted with a solution of unknown concentration to find its concentration.
