mols Mg3N2 = grams/molar mass
Convert mols Mg3N2 to mols NH3 using the coefficients in the balanced equation.
Use PV = nRT to convert mols NH3 to V(in L) at the conditions listed.
Note:This answer is based upon no excess H2O being present since NH3 gas is quite soluble in H2O.
If water is added to magnesium nitride, ammonia gas is produced when the mixture is heated.
Mg3N2(s) + 3 H2O(l) => 3 MgO(s) + 2 NH3(g)
If 11.1 g of magnesium nitride is treated with water, what volume of ammonia gas would be collected at 23°C and 739 mm
