| 1) The mass of the entire solution will add up from the mass of water and the mass of salt dissolved in it. The mass of the entire solution is: 180 + 20 = 200g.
2) Find the mass fraction of salt in the solution. To do this, divide the mass of salt by the mass of the entire solution and multiply by one hundred percent: 20/200 * 100 = 10%.
Answer: the mass fraction of salt in the resulting solution is ten percent.
