Answer 2

Calculating the Mass Fraction of the Solution

To determine the mass fraction of the resulting solution, we can use the formula:

w = (mass of solute / total mass of solution) × 100%

Given: - Mass of the solute (original 15% solution): 300 g - Mass of the solvent (water added): 500 g

Using the given formula, we can calculate the mass fraction of the resulting solution:

w = (300 / (300 + 500)) × 100%

w = (300 / 800) × 100%

w = 37.5%

Therefore, the mass fraction of the resulting solution is 37.5%.
