I need to find the molecular wieght of potassium aluinum sulfate dodecahydrate (I would type the formula, but I'm not sure how to get it in here. Hopefully that is enough info). What does dodeca mean for one thing.

What I think I am confused about is that in the balanced equation (which is all they give of the molecular formula) there are two of one molecule and 12 waters. Should I reduce that? How many atoms are actually in the molecule?

Sorry my question is not very clear. I'm not even sure what I'm asking, but I know I am totally lost (and I hate chemistry...) Any help would be great.

I was always curious. Why does it burn? What chemical properties make it burn?
