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

  • Chemistry -

    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.
