4040 "g/mol"g/mol

Explanation:

Take the sum of the molar masses of each element.

"molar mass of Na"=22.990molar mass of Na=22.990 "g/mol"g/mol
"molar mass of O"=15.999molar mass of O=15.999 "g/mol"g/mol
"molar mass of H"=1.008molar mass of H=1.008 "g/mol"g/mol

The sum is 39.99739.997 "g/mol"g/mol. This can be rounded to an even 4040 "g/mol"g/mol.
