Question

What is the molar mass of KOH?

Answer 1

The molar mass of KOH (potassium hydroxide) is 56.11 g/mol.

Step-by-step explanation:

The molar mass of KOH (potassium hydroxide) can be calculated by finding the atomic masses of the constituent elements from the periodic table. The atomic mass of K (potassium) is 39.10 g/mol, the atomic mass of O (oxygen) is 16.00 g/mol, and the atomic mass of H (hydrogen) is 1.01 g/mol.

To find the molar mass of KOH, we multiply the atomic masses by the number of atoms in the formula: 1 x 39.10 g/mol (K) + 1 x 16.00 g/mol (O) + 1 x 1.01 g/mol (H). This gives us a molar mass of 56.11 g/mol for KOH.

Step-by-step explanation:

Step 1: Define

[Compound] KOH

Step 2: Identify

[PT] Molar Mass of K - 39.10 g/mol

[PT] Molar Mass of O - 16.00 g/mol

[PT] Molar Mass of H - 1.01 g/mol

Step 3: Find

39.10 + 16.00 + 1.01 = 56.11 g/mol
