Step 1:
I'll solve this step-by-step using precise LaTeX formatting:

Step 2:
: Identify the elements and their atomic masses

- Fe (Iron): $$m_{Fe} = 55.85 \mathrm{~g/mol}
- Br (Bromine): m_{Br} = 79.90 \mathrm{~g/mol}

Step 3:
: Count the number of atoms in the compound

- FeBr^3 contains: * 1 Iron atom * 3 Bromine atoms

Step 4:
: Calculate the molar mass by summing the atomic masses

\begin{align}
m_{FeBr_{3}} &= m_{Fe} + 3 \times m_{Br} \ &= 55.85 \mathrm{~g/mol} + 3 \times 79.90 \mathrm{~g/mol} \ &= 55.85 \mathrm{~g/mol} + 239.70 \mathrm{~g/mol} \ &= 295.55 \mathrm{~g/mol} \end{align}

Final Answer

The molar mass of FeBr^3 is 295.55 \mathrm{~g/mol}.
