| Determine the mass of the resulting solution.
m solution = m (water) + m (salt).
m solution = 570 g + 40 g = 610 g.
Determine the mass fraction of salt in the solution.
W = m r.v. / m r-ra * 100%.
W = 40/610 * 100% = 6.6%.
Therefore, the mass fraction of salt in the resulting solution is 6.6 percent.
Answer: W = 6.6%.
