### What is the molar mass of sodium hydroxide? Socratic

May 13, 2016 Truong-Son N. May 13, 2016. The molecular molar mass consists of the atomic masses of each atom. Sodium hydroxide is NaOH. Thus, its molar mass involves: MNa = 22.989 g/mol. MO = 15.999 g/mol. MH = 1.0079 g/mol. So, its molar mass is 22.989 + 15.999 + 1.0079 = 39.996 g/mol to 5 sig figs.
