To calculate the molar mass of F\(_2\) (fluorine gas), you first need the atomic mass of a single fluorine atom (F). The atomic mass of fluorine is approximately 19.0 g/mol.
Since F\(_2\) consists of two fluorine atoms, you would calculate the molar mass of F\(_2\) as follows:
\[
\text{Molar mass of F}_2 = 2 \times (\text{Atomic mass of F}) = 2 \times 19.0 \, \text{g/mol} = 38.0 \, \text{g/mol}
\]
Thus, the molar mass of one mole of F\(_2\) is **38.0 g/mol**.
Since F\(_2\) consists of two fluorine atoms, you would calculate the molar mass of F\(_2\) as follows:
\[
\text{Molar mass of F}_2 = 2 \times (\text{Atomic mass of F}) = 2 \times 19.0 \, \text{g/mol} = 38.0 \, \text{g/mol}
\]
Thus, the molar mass of one mole of F\(_2\) is **38.0 g/mol**.
