Collating
all forms of revenue most sites average around $7 eCPM.
I posted some info on this here:

Specifically with Adsense it varies HUGELY depending on:
- your placement.
- your optimization (colors etc.)
- your niche
- the keywords on your page
- your traffic source
With traffic that comes from search engines on a site that has good high profile placement and is well optimized you should be looking for an average of $3-$7.
For a sites in higher paying niches (e.g business to business, VoIP, high cost consumer products), then adsense eCPM can exceed $10 eCPM - but there is usually less traffic around.
Be aware though that your Adsense earnings will just vary hugely all the time varying by as much as 100% day to day, month to month. Across the board my lowest site had an approx adsense $0.05 eCPM (article directory) and my highest had $80 eCPM (low traffic biz to biz niche). Average was $7.
