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

Step 2:
: Identify the elements in KClO₃

- Potassium (K) - Chlorine (Cl) - Oxygen (O)

Step 3:
: Look up the atomic masses

- Oxygen (O): $$15.999 \mathrm{g/mol}
- Chlorine (Cl): 35.453 \mathrm{g/mol}

Step 4:
: Count the number of atoms

- K: 1 atom - Cl: 1 atom - O: 3 atoms

Step 5:
: Calculate the molar mass by summing the masses

\begin{align}
\text{Molar Mass} &= (1 \times m_{K}) + (1 \times m_{Cl}) + (3 \times m_{O}) \ &= 39.0983 + 35.453 + (3 \times 15.999) \ &= 39.0983 + 35.453 + 47.997 \ &= 122.5483 \mathrm{g/mol} \end{align}

Final Answer

The molar mass of KClO₃ is 122.5483 \mathrm{g/mol}.
