Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the chemical formula
The chemical formula is $$KNO_{3}$$, which means we need to find the molar mass by adding the atomic masses of potassium (K), nitrogen (N), and oxygen (O).
Step 3:: Look up the atomic masses
- Oxygen (O): $$15.9994 \mathrm{g/mol}
- Nitrogen (N): 14.0067 \mathrm{g/mol}
Step 4:: Calculate the molar mass
\begin{aligned}
Molar mass = mass of K + mass of N + mass of 3 oxygen atoms \text{Molar mass} &= 39.0983 + 14.0067 + (3 \times 15.9994) \ &= 39.0983 + 14.0067 + 47.9982 \ &= 101.1032 \mathrm{g/mol} \end{aligned}
Final Answer
The molar mass of potassium nitrate (KNO_{3}) is 101.1032 \mathrm{g/mol}.
