The best you can hope for is a guide...and using GWT (and maybe others, but I have no experience) once you have traffic to ascertain what keywords you're ranking for and how many impressions you're getting.
And when you have data...I bet you will see keywords/phrases that tools tell you have zero...but you're getting impressions from them...or the impressions you are seeing will be well out of volume line with what the tools are telling you.
I would suggest one of the best ways to determine your keywords is.....think like a searcher.
