Dash8Driver is correct.
Just a little addition: of course, performance is a bit dependent on temperature. While I have never had to reject the intention to climb to FL250 yet, high OATs tend to make the last 2-3000ft a chore.
With regards to fuel consumption: at maximum cruise rating and FL250, expect around 330-360kTAS (weight and OAT dependent) and a fuel flow of 2500lbs/h. In case of no performance limits on departure or landing, MZFM allows for 6930lbs of takeoff fuel, so assuming IFR reserves of 1800lbs, a distance of 600NAM should be well feasible; anything beyond that would require lessening the passenger load. Mind You, the MZFM of 57.000lbs is rather generously calculated and in my experience only limiting in case of a full pax load, much luggage plus some cargo - a full pax cabin without cargo will show a ZFM of around 55 to 56.000lbs typically in our operation, so the figures I estimated above are highly conservative. In case You like to calculate for Yourself, a ballpark DOM figure would be at 42.000lbs.
