Molar conductivity of various aqueous solutions?

    I am trying to work out the amount of solute I need to reach a specified conductivity (100 microS/cm^3) for several different solutes.

    An answer to a previous question gave me a method for NaCL using the molar conductivity of aqueous NaCl solution at infinite dilution
    (http://answers.yahoo.com/question/index?qid=20110210095454AAyaOwN&r=w)

    But now I need to find the molar conductivity of other aqueous solutions at infinate dilution to use the method for those other solutes, being:

    1. NaNO3 (Sodium Nitrate)
    2. C3COOH (Acetic Acid)
    3. HCL (Hydrogen Chloride)
    4. HF (Hydrogen Fluoride)

    Is there a place I can find this info or look it up?
    thanks

    http://en.wikipedia.org/wiki/Molar_conductivity

    All necessary formulae should be found on that page.

    surely chemists don't work out these type of stats every single time they want to mix up some saltwater?

    Well I'm just a lowly undergraduate at the moment so I couldn't be sure, however it seems unlikely.
    If I had to guess this is another means of degree examination which I don't particularly agree with.
