Solution

Given mass of NaOH=16 grams $\to$ Solute.
Given mass of water = 100 grams $\to$ Solvent
Solubility (in g/100g) $= \frac{M a s s}{s o l v e n t} \times 100$
$= \frac{16}{100} \times 100 = 16$
Solubility of the solution is 16(g/100g)
Weight Percentage $= \frac{M a s s o f S o l u t e}{m a s s o f s o l u t i o n} \times 100$
$\frac{16 g}{(100 + 16) g} \times 100$
Weight percentage $= 13.79 %$
