Lithium nitride reacts with water to produce ammonia and lithium hydroxide according to the equation Li3N(s)+3H2O(l)⟶NH3(g)+3LiOH(aq) Heavy water is water with the isotope deuterium in place of ordinary hydrogen, and its formula is D2O. The same reaction can be used to produce heavy ammonia, ND3(g), according to the equation Li3N(s)+3D2O(l)⟶ND3(g)+3LiOD(aq) Calculate how many grams of heavy water are required to produce 135.0 mg ND3(g). The mass of deuterium, D, is 2.014 g/mol. mass: g D2O ?
