Which element has an atomic number of 19?
Fluorine is a non metal element. Atomic mass number of it is 19.
What is the atomic mass of element f?
The atomic mass of an element is the weighted average mass of its isotopes. To determine the atomic mass of element F, you would need to know the abundance of each isotope and its individual atomic mass, and then calculate the weighted average based on those values.
What is the atomic mass of F?
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
What is symbol atomic number atomic mass of fluorine?
According to the periodic table: F atomic number 9, atomic mass of 18.998403
What is the average atomic mass for gallium if 60.00 percent of its atoms have a mass of 68.026 amu and 40.00 percent have a mass of 70.925 amu?
aright so lsn up bi**** and dumb a**** of all ages who cant answer this f****** simple question. you will fail if u dont knw it fa*****. all u do is 60.00 x 68.026 + 70.925 x 40.00... n whatver the f*** u get u divide it by 100!!! f***ing simple isnt it fa*****?

What is the average atomic mass of fluorine?
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.
How to calculate the percent composition of F in NaF?
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.
What is the mass number of F?
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
What is the formula mass for NaF?
The formula mass of NaF (sodium fluoride) is calculated by adding the atomic masses of sodium (Na) and fluorine (F) together. The atomic mass of Na is approximately 22.99 g/mol, and the atomic mass of F is approximately 18.99 g/mol. Therefore, the formula mass of NaF is approximately 22.99 + 18.99 = 41.98 g/mol.
