Molar Mass of KOH

How to work out the molar mass of KOH

1. Count the atoms of each element in KOH: 1 K, 1 O and 1 H.
2. Multiply each count by the element's atomic weight: 1 × 39.098 = 39.098; 1 × 15.999 = 15.999; 1 × 1.008 = 1.008.
3. Add the results: 39.098 + 15.999 + 1.008 = 56.105 g/mol.

Frequently asked questions
