The mass of an atom is typically expressed in atomic mass units (amu) or in grams per mole (g/mol). The atomic mass unit (amu) is a unit of mass commonly used for expressing atomic and molecular weights on a scale relative to the carbon-12 isotope.
The atomic mass of fluorine (F) is approximately 18.9984 atomic mass units (amu). Therefore, the mass of one fluorine atom is approximately 18.9984 amu.
To convert this mass to grams, you can use the Avogadro constant, which is approximately 6.022 × 10^23 atoms/mol. This constant represents the number of atoms or molecules in one mole of a substance.
To convert from amu to grams, you divide by Avogadro's number:
Mass in grams = (Atomic mass in amu) / Avogadro's number
Let's calculate the mass of one fluorine atom in grams:
Mass in grams = 18.9984 amu / (6.022 × 10^23 atoms/mol)
Mass in grams = 3.16 × 10^(-23) grams
Therefore, the mass of one fluorine atom is approximately 3.16 × 10^(-23) grams.
