Answer 1

Answer #1

Balanced equation for this reaction is,

3H2O + Mg3N2 --------> 3MgO + 2NH3

3 moles of H2O gives 2 moles of NH3.

1 mole of will give 2/3 moles of NH3 i.e. 0.667 moles

Moles of NH3 formed by 2.20 moles H2O = 2.20 × 0.667

= 1.467 moles

Theoretical yield = 1.467 moles

Percent yield = (actual yield/theoretical yield)×100

Actual yield = 0.823 moles

Percent yield = (0.823/1.467) × 100

= 56.0 %

Answer = 56.0 %
