How do you Find the Percent Composition of Oxygen in Sodium Hydroxide

Answer: The inorganic compound sodium hydroxide, also recognized as lye as well as caustic soda, has the formula NaOH. It is indeed a white strong ionic compound containing sodium cations Na+ as well as hydroxide anions OH–. Sodium hydroxide is indeed a caustic base as well as alkali that degrades proteins at room temperature and can cause serious chemical burns. It soaks up moisture as well as carbon dioxide out from the air and is heavily soluble in water. It creates a set of NaOH . nH₂O hydrates.

NaOH molar mass =23+16+1=40

∴ percentage composition of O₂= 16/40 ×100=40%

The percentage composition of O₂ in sodium hydroxide = 40.000%.
