To a solution with a mass of 150 g with a mass fraction of sucrose of 10% was added 50 g

To a solution with a mass of 150 g with a mass fraction of sucrose of 10% was added 50 g of sugar. The mass fraction of sucrose in the new solution is …

Progress in solving the problem:
1) Calculation of the mass of the solute sucrose in a 10% solution. To do this, we multiply the mass fraction of the substance by the mass of the solution and divide by one hundred percent.
2) Calculation of the mass of the solute sucrose in the resulting solution. Add the found mass of the solute and the mass of added sucrose.
3) Calculation of the mass of the solution after adding sucrose.
4) Calculation of the mass fraction of sucrose in the resulting solution.
Solution:
1) 150 * 10/100 = 15g.
2) 15 + 50 = 65g.
3) 150 + 50 = 200g.
4) 65/200 * 100 = 32.5% -res.
