| 1) Find the mass of the solution after dissolving salt and water. To do this, add the mass of salt and the mass of water: 90 + 10 = 100g.
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: 10/100 * 100 = 10%.
Answer: the mass fraction of salt in the solution is ten percent.
