Understanding the molar mass of potassium hydroxide (KOH) is essential for various applications, from chemical experiments to industrial processes. Potassium hydroxide, a strong base, plays a crucial role in industries like soap making, battery production, and water treatment. Knowing its molar mass helps in precise measurements and reactions. Let’s dive into the details to simplify this concept for both informational and commercial purposes.
What is the Molar Mass of Potassium Hydroxide?
The molar mass of KOH is the sum of the atomic masses of its constituent elements: potassium (K), oxygen (O), and hydrogen (H). Using the periodic table, we find:
- Potassium (K): 39.10 g/mol
- Oxygen (O): 16.00 g/mol
- Hydrogen (H): 1.01 g/mol
Adding these values together:
Molar Mass of KOH = 39.10 + 16.00 + 1.01 = 56.11 g/mol
📌 Note: Always ensure accurate atomic masses for precise calculations.
How to Calculate Molar Mass: Step-by-Step Guide
- Identify the Chemical Formula: Potassium hydroxide is represented as KOH.
- Find Atomic Masses: Use the periodic table to locate the atomic masses of K, O, and H.
- Sum the Masses: Add the atomic masses of all elements in the formula.
| Element | Atomic Mass (g/mol) |
|---|---|
| Potassium (K) | 39.10 |
| Oxygen (O) | 16.00 |
| Hydrogen (H) | 1.01 |
| Total (KOH) | 56.11 |
