Questions: What is the mass of a sulfur tetrafluoride molecule?

Solution Steps

The molecular formula for sulfur tetrafluoride is \( \text{SF}_4 \).

• The atomic mass of sulfur (S) is approximately 32.06 amu (atomic mass units).
• The atomic mass of fluorine (F) is approximately 19.00 amu.

The molecular mass of \( \text{SF}_4 \) is calculated by adding the atomic masses of one sulfur atom and four fluorine atoms:

\[ \text{Molecular mass of } \text{SF}_4 = 32.06 + 4 \times 19.00 = 32.06 + 76.00 = 108.06 \, \text{amu} \]

The molecular mass in amu is numerically equivalent to the molar mass in grams per mole. Therefore, the molar mass of sulfur tetrafluoride is 108.06 grams per mole.
