what is the molar mass of fluorine, f2?\n9.00 g/mol\n18.00 g/mol\n19.00 g/mol\n38.00 g/mol

Explanation:

Step1: Recall atomic mass of F

The atomic mass of a single - fluorine atom (F) is approximately 19.00 g/mol.

Step2: Calculate molar mass of F₂

F₂ is a diatomic molecule. So, the molar mass of F₂ is 2 times the atomic mass of F. $M_{F_2}=2\times19.00\ g/mol = 38.00\ g/mol$

Answer:

D. 38.00 g/mol
