Examples: Sulfuric Acid 93%, Sulfuric Acid 5% v/v Aqueous Solution, Sulfuric Acid 10% w/w Aqueous Solution, Silver Nitrate 0.025 Normal.
How do I relate this to molarity and what does v/v, w/w, and normal mean?

Any help? I just need to know so that I can choose when purchasing chemicals.

v/v means volume to volume, so it would be 5% by volume sulfuric acid, and 95% by volume water (aqueous).
w/w means weight to weight, so 10% by weight sulfuric acid and 90% by weight water. Here's a site that actually offers explanations to all your questions, and it does a better job than I could explaining normality. http://environmentalchemistry.com/yo...Normality.html
