Looking for dimensional analysis problems/solutions

[Mholnic-]

I wasn't sure whether to put this here or in the Chemistry forum, so if it's in the wrong place I'd prefer it be moved rather than deleted. ;) Anyway.

I'm struggling a bit with Dimensional Analysis, particularly of volumes/density and recognizing conversion factors when I see them. As more and more variables are introduced, the problem just gets away from me. Given that my book doesn't have solutions to most of the problems and there aren't very many problems to begin with, I have a hard time recognizing when and where I mess up.

Does anyone know where I can find some problems online? Preferably with solutions, and bonus points if they show their work. I've found a few tutorials and small groups of problems through a standard Google search, but was hoping someone would know where I could find a great deal more -- perhaps from a university chemistry department website somewhere.

Thanks.

You'll find some places online if you Google "dimensional analysis problems".
