Question

Quizplus · Accepted Answer

To calculate the mass percent, we need to divide the mass of solute (NaOH) by the total mass of solution (NaOH + water) and multiply by 100:

Mass percent = (5 g / (5 g + 25 g)) x 100% = 16.7%

Therefore, the solution is not a 20 mass % NaOH solution, so the answer is false.
