Solving a chemistry problem

3. To 25.00 ml of hydroxylamine hydrochloride solution, 25.00 ml of 0.1 N KBrO3 solution (feq = 1/6) (K = 0.9876) was added:
NH2OH*H BrO3-↔NO3- Br-2H H2O
Excess bromate was titrated iodometrically, using 15.00 ml of thiosulfate solution with T(Na2S2O3) = 0.01634. Determine the concentration (g/l) of the hydroxylamine NH2OH solution.
