sodium hydroxide = NaOH

By Atom to Atom Ratio:

Na = sodium = 33.333%

O = oxygen = 33.333%

H = hydrogen = 33.333%

but if you mean mass ratio, then

Na =23g

O = 16g

H = 1g

23g+16g+1g=40g

therfore 23g/40g x 100

sodium (Na) percentage, by mass, is 57.5% (exact) in the total mass of sodium hydroxide NaOH
