5 g of salt was dissolved in water weighing 60 g. what is the mass fraction of salt in the solution?

Progress in solving the problem:
1) Calculation of the mass of the entire solution. To do this, add the mass of water and the mass of salt added to the solution 60 + 5 = 65g.
2) Find the mass fraction of salt in the resulting solution. To do this, divide the mass of the dissolved salt by the mass of the solution and multiply it by one hundred percent.
1) 60 + 5 = 65g.
2) 5/65 * 100 = 7.7%.
Answer: The mass fraction of salt in the resulting solution will be equal to 7.7%.
