Step 1:I'll solve this problem step by step, following the LaTeX formatting guidelines precisely:
Step 2:: Identify the atomic mass of fluorine
- From the periodic table, the atomic mass of fluorine (F) is $$19.00 \mathrm{g/mol}
Step 3:: Calculate the molar mass of \mathrm{F}_{2}
- $$\mathrm{Molar~mass} = 38.00 \mathrm{g/mol}
- Since this is a diatomic molecule, we multiply the atomic mass by 2
Step 4:: Verify the calculation
- $$19.00 \mathrm{g/mol} \times 2 = 38.00 \mathrm{g/mol}
Final Answer
Key Insights: - For diatomic molecules, multiply the atomic mass by the number of atoms - Always check the periodic table for accurate atomic masses - Carefully count the number of atoms in the molecular formula
