The question "How to calculate BF3?" is somewhat ambiguous. It could refer to different calculations. Based on the provided reference, we can calculate the molar mass of BF3 and the mass of BF3 in a given number of moles. Let's clarify and address these calculations.
Calculating the Molar Mass of BF3
Molar mass is the mass of one mole of a substance. Here's how to calculate the molar mass of Boron Trifluoride (BF3):
- Boron (B): The molar mass of Boron is 10.81 g/mol.
- Fluorine (F): The molar mass of Fluorine is 19.00 g/mol. Since there are three fluorine atoms in BF3, we multiply this by 3, resulting in 57.00 g/mol (3 * 19.00 g/mol).
- Total Molar Mass: Add the molar mass of Boron and the total molar mass of Fluorine: 10.81 g/mol + 57.00 g/mol = 67.81 g/mol.
Therefore, the molar mass of BF3 is 67.81 g/mol.
Calculating Mass of BF3 given Moles
The provided reference also demonstrates how to calculate the mass of BF3 in grams given a number of moles. Let's take the example from the reference, which uses 1.56 moles of BF3.
- Molar Mass of BF3: 67.81 g/mol (as calculated above)
- Moles of BF3: 1.56 mol
- Mass of BF3: Multiply the molar mass by the number of moles: 67.81 g/mol * 1.56 mol = 105.77 grams.
Therefore, there are 105.77 grams of BF3 in 1.56 moles.
Summary
The question "How to calculate BF3?" can involve calculating the molar mass of BF3 or the mass of BF3 given a certain number of moles.
| Calculation | Steps | Result |
|---|---|---|
| Molar Mass of BF3 | Add the atomic mass of Boron and three times the atomic mass of Fluorine | 67.81 g/mol |
| Mass of BF3 (1.56 mol) | Multiply the molar mass of BF3 by the given number of moles (1.56 mol) | 105.77 grams |
In short, to calculate the molar mass of BF3, sum the atomic mass of boron with three times the atomic mass of fluorine. To calculate the mass of BF3 given the moles, simply multiply the number of moles by the molar mass of BF3.
