INTERNATIONAL MARITIME COLLEGE OMAN PO1681-2 Question 2 (5 Marks) (MLO 2, 3, 5, analyse, apply, suggest) A sample of magnesium nitrate, Mg(NO3)2 (FM 148.31), weighed 0.282 8 g was dissolved in 1 wt% HF (aq) and then treated with nitron (C20H16N4, FM 312.37) solution to precipitate nitron nitrate (C20H17N5O3, FM 375.39) weighing 1.322 g. The structure of nitron and nitron nitrate are shown in the figure bellow.
