The mass of NaOH present in the solution is, 0.0625 grams
The mass is defined as the quantity of the matter present in the solution or in any substance.
Given that,
Mass % of NaOH in the solution= 25 %
Mass of solution = 0.250 g
The formula will be
[tex]\rm Mass\ percent=\dfrac{mass \ of\ NaOH}{Mass\ of\ solution} \times 100[/tex]
[tex]25=\dfrac{\rm Mass\ of \ NaOH}{0.250} \times 100[/tex]
Mass of NaOH=0.0625 gram
Thus the mass of NaOH present in the solution is, 0.0625 grams

The mass of NaOH present 0.250 grams of solution is 0.0625 grams.
Mass of any substance present in any solution will be calculated by using their & mass as below:
Mass percent = (Mass of solute / Mass of solution) × 100
Given items according to the question,
% mass of NaOH = 25%
Mass of solution = 0.250g
Now e put these values on the above equation and we get,
Mass of NaOH = (5 × 0.250) / 100 = 0.0625 grams.
Hence, mass of NaOH is 0.0625 grams.
