Determination of the Formula of a Compound

Extracts from this document...


Determination of the Formula of a Compound Results Mass of crucible and lid 23.0899g Mass of crucible, lid and Mg 23.1535g Mass of crucible, lid and product 23.1894g Mass of Mg used = 0.0636g (Mass of crucible, lid and Mg 23.1535 - Mass of crucible and lid 23.0899) ...read more.


Mg mass used 0.0636 Ratio Mean Mass of O used 0.0359 Atomic Mass 24 Atomic Mass 16 =0.00265 =0.00224375 Divide the smallest by the largest (0.00265/0.00224375) gives the ratio number of mole. Mg: 1.18105 O: 0.08466 Conclusion Oxygen is a very good oxidizing agent. ...read more.


These results have not shown a yield exact (simple) ratio. So these calculations show my results not to be entirely accurate. There may be several causes for this. The most obvious cause may have been due to experimenters error. The crucible lid may have been lifted to often allowing too much oxygen to react with the magnesium. The atoms are rearranged - diatomic oxygen molecules are split apart so that one oxygen atom combines with one magnesium atom. ...read more.

  1. Identification of an unknown compound.

    Analysis A negative result was observed in test 1 for a phenol as no decolourisation of bromine water occurred and no white precipitate formed. This indicated the absence of a phenol and after this, test 2 was carried out. Test 2 using orange 2,4-dinitrophenylhydrazine solution was positive as an orange/red 2,4-dinitrophenylhydrazone precipitate was observed.

  2. The role of mass customization and postponement in global logistics

    Mass Customization, the production of unique products at a mass produced cost, sounds like a contradiction, but by using the new interactive mediums it's now possible to meet the individual needs of customers in a mass market and make superior profits.

  1. Relationship between mass of MgO and its formula

    To try and see if my hypotheses are correct I did a preliminary experiment. Preliminary Expt. Method Measure the weight of the crucible and the lid with and without the magnesium in it before and after it has been oxidised.

  2. Finding the empirical formula of aluminium chloride.

    Random errors- which depend on the experimenters ability to use the apparatus. In this case, making a number of readings of a given quantity, i.e. repeating a titration, and taking an average will reduce the overall error. In light of our results, it appears that the systematic error is
