Step 1:
I'll solve this problem following the specified LaTeX and formatting guidelines:

Step 2:
: Identify the Chemical Name

The chemical formula Fe₂O₃ represents iron(III) oxide, also known as ferric oxide. The Roman numeral (III) indicates the oxidation state of iron in this compound.

Step 3:
: Determine the Atomic Masses

- Iron (Fe): $$m_{Fe} = 55.85 \mathrm{~g/mol}
- Oxygen (O): m_{O} = 16.00 \mathrm{~g/mol}

Step 4:
: Calculate the Molar Mass

\begin{align}
- Number of Fe atoms: 2 - Number of O atoms: 3 Molar mass calculation: m_{Fe_{2}O_{3}} &= (2 \times m_{Fe}) + (3 \times m_{O}) \ &= (2 \times 55.85) + (3 \times 16.00) \ &= 111.70 + 48.00 \ &= 159.70 \mathrm{~g/mol} \end{align}

Final Answer

- Chemical Name: Iron(III) oxide (Ferric oxide) - Molar Mass: 159.70 \mathrm{~g/mol}
