Molecular weight (mass):

It is the molecular mass of a substance that can be calculated by sum of atomic weight of atoms that are present in the molecule multiple by the total number of molecule.

In KOH,

Atomic weight of K=39.1

Atomic weight of O=15.9

Atomic weight of H=1

Molecular weight=Atomic weight of K+Atomic weight of O+Atomic weight of H

=56.1 g/mol

So the answer is A that is 56.10 g/mol
