There is no element called 'flouorine', however there is one called fluorine. What is it's atomic mass? It depends how accurate you want the answer, for most of us 19.0 is accurate enough. Mike Slater 19.0 is inappropriate, given that .0 is a significant figure and will be assumed to be correct. 19 would be more appropriate, and 18.998 would be more accurate.
