Actually massnumbers are only given to (isotopes) of elements.

If you want to know the molecular mass, molar mass one should add up all atomic masses (not the same as 'mass numbers') of that molecule:

Na=22.98977, O=16.00, H=1.008, so the molar mass of NaOHis 39.998 = 40.00 g/mol.

(Note that atomic masses are not exact, but rounded numbers, while mass numbers are exact quantities (whole numbers): Na=23, O=16, 17, 18 and H=1)

How its made 2 M solution of Na OH?

First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.
