Answer:
Percent yield = 88.23%
Explanation:
Given data:
Percent yield of ammonia = ?
Actual yield = 15 g
Mass of nitrogen = 14 g
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Number of moles of nitrogen:
Number of moles = mass/molar mass
Number of moles = 14 g/ 28 g/mol
Number of moles = 0.5 mol
Now we will compare the moles of ammonia and nitrogen.
N₂ : NH₃
1 : 2
0.5 : 2/1×0.5 = 1 mol
Mass of ammonia/Theoretical yield
Mass = number of moles × molar mass
Mass = 1 mol × 17 g/mol
Mass = 17 g
Percent yield:
Percent yield = ( actual yield / theoretical yield )× 100
Percent yield = (15 g/ 17 g)× 100
Percent yield = 88.23%
