Chadwick discovered the existence of neutrons which accounts for isotopy.
Isotopes exists because atoms of the same element may differ in the number of neutrons present in each one. This phenomenon is called isotopy.
Chadwick discovered the existence of isotopes by bombarding Beryllium with alpha particles obtained from Polonium decay.
The discovery of the existence of neutrons led us to the a better understanding of isotopes since isotopes differ only in the number of neutrons present.

Yeah it’s that
First you have to find the molar mass of the compound. In order to do this, you add together the molar masses of each element in the compound.
Then you divide your starting mass by the molar mass in order to get the amount of moles.
So your answer is 1.5 mols of NaOH
