What is the molar mass of NaOH

The molar mass of NaOH (sodium hydroxide) is calculated by adding the atomic masses of sodium (Na), oxygen (O), and hydrogen (H).

The atomic mass of sodium (Na) is 22.99 g/mol.
The atomic mass of oxygen (O) is 16.00 g/mol.
The atomic mass of hydrogen (H) is 1.01 g/mol.

So, the molar mass of NaOH is:
22.99 g/mol (Na) + 16.00 g/mol (O) + 1.01 g/mol (H) = 39.99 g/mol
