Quantative Chemistry
  1. Empirical Formula
    1. 1) write % mass next to each element in compound
      1. 2) Divide each mass % by the atomic mass for element
        1. 3) Divide both numbers by smallest number
    2. Percentage Mass
      1. 1) calculate formula mass of compound
        1. 2) Divide atomic mass of element wanted by overall formula mass
          1. 3) Multiply by 100
      2. Relative Formula mass
        1. the amount of all elements in the compound
          1. molecular masses added together
        2. the atomic mass in g = 1 mole
          1. 1 mole of carbon= 12g
            1. 1 mole of calcium=40g
          2. Percentage Yields
            1. actual amount/theoretical amount x 100
            2. predicting masses
              1. balance equation
                1. calculate molecular mole in masses
                  1. divide to make 1g
                    1. multiply to make amount needed
