What is the molar mass of BF3?

The molar mass of BF₃ (Boron Trifluoride) can be calculated by adding the molar masses of its constituent elements: boron (B) and fluorine (F).

Boron has a molar mass of approximately 10.81 g/mol, and fluorine has a molar mass of about 19.00 g/mol. Since there are three fluorine atoms in BF₃, we multiply the molar mass of fluorine by three:

• Boron: 10.81 g/mol
• Fluorine: 3 × 19.00 g/mol = 57.00 g/mol

Now, we can add these values together:

Molar Mass of BF₃ = 10.81 g/mol + 57.00 g/mol = 67.81 g/mol

Therefore, the molar mass of BF₃ is approximately 67.81 g/mol.
