If not, you can search it on google, you have to create your blog on the site blogger.com, there are various other sites too, but you have to keep your blog updated for at least 6 months, then you have to send application for approval and it will be approved.
This is the information, as per my knowledge, please consult others too.
Have you registered it under google adsense earlier, before making the site..??
In my views, not every site can come under adsense program, if you have already register it under adsense program and then make it, then only it gets approved.
You can google your query as such.. that "How to get my site google sdsense approval for free?"
I am sure, you will get some helpful content.
