Chemistry Questions

    Just a few questions I have and I cannot seem to find any good explanations in the book:

    1) How do you calculate mass yield of a solution?

    2) How do you calculate the number of moles used in a titration?

    Any help is greatly appreciated.

    Mass yield:
    I believe this has to use some stoichiometry. So first write a balanced equation.

    Next figure out your initial numbers, and use the mole ratio to convert say from substance A to substance B. When you get the moles of substance B, you can then convert that into its molar mass.

    As for titrations, same idea. Figure out how much of a substance A you used in the titration, and then convert that into moles, provided that you have a balanced equation.

    This is all of the top of my head, so what I say might be close to what you actually got to do.
