| The solution consists of salt and water.
The mass of the solution will be equal to the mass of these two substances.
M solution = m salt + m water = 125 + 5 = 130 grams;
The mass fraction of salt is equal to the ratio of the mass of salt to the mass of the solution.
Let’s find this value.
W salt = 5/130 = 0.038 = 3.8%.
