How much data per month will I use?

I recently purchased a Motorola Droid 2 from Verizon where I purchased 2 GB of data. If I use the internet for sites like MSN, ESPN, and normal Google searches and I use the weather app pre downloaded will I go over my limit? Also I will probably view 20 emails per day. Thanks|||u shoud be fine at like 25 webpages a day and 50 emails a day thats about 1.11 gbs of data per month so any weather app u use shouldnt put u over to much and thats 50 emails and 25 webpages per day and u said less than that so as long as ur not watching videos or anyyhing u shoud be fine
