TOPIC 3

• cm^3 to dm^3 is?


  divide by 1000
• formula for moles


  moles= mass(g) / mr
• percentage by mass formula


  percentage by mass= mass of product / maximum theoretical mass of product x 100
• concentration?


  concentraion= moles/volume (dm^3)
• percentage yield formula


  percentage yield= mass of product / maximum theoretical mass of product x 100
• atom economy


  mr of desired/sum of mr of reactants
• volume of gas =


  mole x 24
