The molar mass of sulfur hexafluoride (SF6) is 146.06 g/mol. This value is calculated by adding the atomic masses of its constituent elements:
- Sulfur (S): 32.07 g/mol
- Fluorine (F): 19.00 g/mol
Since there are six fluorine atoms in sulfur hexafluoride, we need to multiply the molar mass of fluorine by six:
32.07 g/mol (S) + 6 × 19.00 g/mol (F) = 32.07 g/mol + 114.00 g/mol = 146.07 g/mol
Therefore, the molar mass of sulfur hexafluoride is approximately 146.06 g/mol, which is typically rounded to 146 g/mol for calculations. This knowledge is essential in stoichiometry and various chemical calculations.
