First, we find the mass of the solution, for this we translate 375 ml of water = 375 g:
m solution = m solute + m (H2O)
m solution = 25 + 375 = 400 g
Now we find the mass fraction of salt in the solution:
w = (m solute / m solution) * 100%
w = (25/400) * 100% = 6.25%
Answer: the mass fraction of salt in the resulting solution is 6.25%
