Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the elements in potassium hydroxide (KOH)
- Potassium (K) - Oxygen (O) - Hydrogen (H)
Step 3:: Look up the atomic masses of each element
- Hydrogen (H): $$1.00794 \mathrm{g/mol}
- Oxygen (O): 15.9994 \mathrm{g/mol}
Step 4:: Calculate the molar mass by adding the atomic masses of all atoms
\begin{aligned}
\text{Molar Mass} &= m_{K} + m_{O} + m_{H} \ &= 39.0983 + 15.9994 + 1.00794 \ &= 56.1056 \mathrm{g/mol} \end{aligned}
Final Answer
The molar mass of potassium hydroxide (KOH) is 56.1056 \mathrm{g/mol}.
