Adsense doesn't pay per impression, it pays per click. Therefore, what you can get for 1000 impressions (CPM) varies by how many people click (CTR) and how much money that particular click pays (CPC). If you want a range, I can't give you anything that would help, because for 1000 impressions you could make from $0 to $100+ all depending on those factors mentioned above.
First, welcome to WW and the Adsense forum.
On top of what others have said here it's important to know about "Smart Pricing". That is a system Google uses to decide what they will pay publishers for clicks. It basically means that a single click could pay $0.10 on one site and $0.50 on another site.
All in all, this stuff adds up to making it nearly impossible to even suggest a realistic range of earnings.
