The first step is to find the molar mass of NaOH. This can be done by combining the molar mass of all of the elements inside of it. Na, or sodium, has a molar mass of about 23. Oxygen has a molar mass of about 16, and hydrogen has a molar mass of about 1. Adding all of these together, you get a total molar mass of 40. This means that a single mole of NaOH weighs 40 grams, which is the mass of NaOH that needs to be weighed out. Hope this helps!
