67. Solving a chemistry problem

1. A weighing of 1.215 g of magnesium sulfate was dissolved in a volumetric flask with a capacity of 100 ml. For titration of 10.0 ml of the resulting solution, 9.0 ml of a 0.1 mol/l solution of Trilon B is consumed. Determine the mass fraction of magnesium in the solution. Write the equation for the ongoing reaction. Draw up a titration scheme.
