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