 # What is the molecular weight of NaOH?

Sodium Hydroxide is a solid ionic compound. Sodium Hydroxide is a white, translucent crystalline solid. It is commonly referred to as caustic soda due to its corrosive action on many substances it decomposes proteins at room temperatures and may cause chemical burn to human bodies.

Alternative names

It is also known as caustic soda, Iye, sodium hydrate or soda lye.

## Molecular weight

The weight in atomic mass units of each of the atoms in a given formula is the molecular weight of a substance.

### Molecular weight of NaOH

Take the sum of the molar masses of each element.

molar mass of Na =22.990 g/mol

molar mass of O = 15.999 g/mol

molar mass of H =1.008 g/mol

On adding up all the above masses we get

22.990 g/mol + 15.999 g/mol + 1.008 g/mol= 39.997 g / mol or 40 g / mol
