Fluorine is a non metal element. Atomic mass number of it is 19.
Answer #1 The Atomic Mass for Flourine (F) is 18.9Answer #2 If by F you mean fluoride you can find the atomic mass on any periodic table, which is 18.993
If by f you mean the element fluorine, it typically comes in the form of two-atom molecules.
The atomic mass of I is 127. The atomic mass of F is 19. Therefore the molecular mass of the compound is 127+5x19=214u.
According to the periodic table: F atomic number 9, atomic mass of 18.998403

Answer #1 The Atomic Mass for Flourine (F) is 18.9Answer #2 If by F you mean fluoride you can find the atomic mass on any periodic table, which is 18.993
Atomic Mass: 18.998404
If by f you mean the element fluorine, it typically comes in the form of two-atom molecules.
The atomic mass of I is 127. The atomic mass of F is 19. Therefore the molecular mass of the compound is 127+5x19=214u.
According to the periodic table: F atomic number 9, atomic mass of 18.998403
Symbol - F Atomic Number - 9 Mass Number - 19
To find percent composition, you must work with the atomic masses. Look on a periodic chart to find the atomic masses of F and Na. You will find that Na has an atomic mass of 22.990 grams per mole of Na and that F has an atomic mass of 18.998 grams per mole of F. So, add these both together, and that will tell you how much mass NaF will be. NaF will have a mass of 41.988 grams per mole of NaF. Now to take the percent composition of F in NaF, simply divide the mass of F by the mass of NaF. That will give you [18.998/41.988]=.452 which will be about 45%. So your answer is that F has a 45% composition of NaF. PS: Since Na and F only had a stoichiometry of 1 (meaning there is 1 Na and 1 F in the molecule), no multiplication of the atomic masses was necessary when calculating the total mass of the molecule.

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.
