  • Chemistry 2
    • Percentage mass of element= Relative atomic mass x no of atoms(in element) / the relative formula mass. All times by 100
    • THE EMPIRICAL FORMULA
      • 1. List the elements
      • 2. Write there experimental  mass number
      • 3. Divide by  the relative atomic mass
      • 4. Multiply by good number such as 10
        • 5. And/or divde them
          • 6. Get into simplest form yand you have the empiracal formula of that compound
    • Amount of product you get is a yield
      • percentage yield= actual yield(grams)/ predicted yield(grams) x100
    • Rate of reaction depends on four things: 1. temperature, 2.concentration, 3. catalyst, 4. surface area
    • Rate of reaction= amount of reactant used or amount of product formed/ time
  • 5. And/or divde them
    • 6. Get into simplest form yand you have the empiracal formula of that compound
