What mass of aluminum is required to react with 100.0 ml of 6.00M
hydrobormic acid to produce 24.5 mg? (show work) And what type of
reaction is it?

Open a textbook and study.

I've been looking over my textbook for 4 hours trying to find how to
do this. I don't know how, so instead of making smart comments, it'd
be alot more useful to tell me how to do it. I just figured if I'm
gonna pay $10, I should get the answer as well as the how to.
