Density Relationships - Cant find any good sources.

  1. Nov 9, 2009 #1
    Im working on the conclusion for my lab report, and rather than plagiarize the work like most I know, Im trying to write it myself. Ive spent probably between 30-40 hours on it so far, so dont think im trying to cheat or get ahead here. But I need to describe relationships of density to other concepts in my conclusion. Id also enjoy some advice on how to correctly write the conclusion to a formal lab report in a chemistry class.

    Now according to me teacher, some things to look into were density compared to:

    molecular bonding
    physical properties
    state or matter
    electron structure
    atomic theory
    atomic structure

    are there any other relationships between density and other concepts?

    Also, if someone could point me to some good, credible sources on the internet, I would greatly appreciate it. It seems everything Ive found over the past two hours is either not enough in depth, or is so particular it has nothing to do with density.


    Im gona keep looking for good sources, but if someone can help me out, I will really appreciate your help!

    Thanks,
    -Ryan

    Here is another suggestion: molecular size and shape might be important. Some molecules may fit in the spaces between other molecules, allowing closer packed use of space and by this causing increased density of a mixture of certain compounds. This might be in effect for mixing water and ethanol. The volumes of the separate compounds do not simply add directly but instead the result volume is less.

    ...Of course, my suggestion may be wrong, and the lower volume of the mixture might be due to attraction between the two compounds. I do not know which idea is more correct.
