The molecular weight of potassium hydroxide (KOH) can be calculated by adding the atomic weights of its constituent atoms.
The atomic weights are as follows:
Potassium (K): 39.10 g/mol
Oxygen (O): 16.00 g/mol
Hydrogen (H): 1.01 g/mol
Adding these atomic weights together gives the molecular weight of KOH:
Molecular weight of KOH
=
Atomic weight of K
+
Atomic weight of O
+
Atomic weight of H
Molecular weight of KOH=Atomic weight of K+Atomic weight of O+Atomic weight of H
Molecular weight of KOH
=
39.10

g/mol
Molecular weight of KOH=39.10+16.00+1.01g/mol
Calculating this gives the molecular weight of KOH as approximately 56.11 g/mol.
