Step-by-Step Guide to Calculate the Molar Mass of BF3
Step 1: Identify Atomic Masses
Refer to the periodic table for the atomic masses of boron (B) and fluorine (F).
- Boron (B): Approximately 10.81 g/mol
- Fluorine (F): Approximately 19.00 g/mol
📌 Note: Ensure you use precise atomic masses for accurate calculations.
Step 2: Determine the Molecular Formula
BF3 consists of one boron atom and three fluorine atoms. This formula is essential for calculating the total molar mass.
Step 3: Calculate the Molar Mass
Add the atomic masses of all atoms in the molecule:
[
\text{Molar Mass of BF3} = (1 \times \text{B}) + (3 \times \text{F})
]
[
\text{Molar Mass of BF3} = (1 \times 10.81) + (3 \times 19.00)
]
[
\text{Molar Mass of BF3} = 10.81 + 57.00 = 67.81 g/mol
]
| Element | Atomic Mass (g/mol) | Number of Atoms | Total Mass (g/mol) |
|---|---|---|---|
| Boron (B) | 10.81 | 1 | 10.81 |
| Fluorine (F) | 19.00 | 3 | 57.00 |
| Total Molar Mass of BF3 | 67.81 | ||
