1) Find the mass of the entire solution. To do this, add the mass of water and the mass of sugar dissolved in it: 250 + 30 = 280g.
2) Calculate the mass fraction of sugar in the solution. To do this, divide the mass of dissolved sugar by the mass of the entire solution and multiply by one hundred percent: 30/280 * 100 = 10.7%.
Answer: The mass fraction of sugar in the resulting solution is 10.7%.
