I am kinda confused here. An article on Zeocarbon (activated charcoal) from Wikipedia states that Zeocarbon typically has a **surface area** in excess of 500 square meters per gram.

Here’s my question… How can 1 gram of a substance have that much surface area??? I’m not saying it’s not possible or that information provided is false, neither am I challenging any of it. Just asking **how** is it possible and what exactly is the **surface area** they’re talking about there?

Any chemistry experts here?

I’m kinda curious… Again! 😛
