Answer:
The theoretical yield of NH3 = 54.9 grams
The actual yield of NH3 = 26.5 grams
The % yield = 48.3 %
Explanation:
Step 1: Data given
Mass of NH3 produced = 26.5 grams
54.9 grams of NH3 was predicted
Step 2: The balanced equation:
CaO(s) + 2NH4Cl(s) → 2NH3(g) + H2O(g) + CaCl2(s)
Step 3: Theoretical yield
The theoretical yield, is the amount of NH3 that is predicted to be formed = 54.9 grams
The actual yield is the amount of NH3 that actual has been formed = 26.5 grams
% yield = (actual yield / theoretical yield)*100 %
% yield = (26.5 grams / 54.9 grams) * 100%
% yield = 48.3 %
The percentage yield of ammonia is 48.6 %. Percentage yield can be calculated by the ratio of actual yield to theoretical yield.
How to calculate percentage yield?
Percentage yield can be calculated by the ratio of actual yield to theoretical yield.
Theoretical yield is the predicted value of the produced compound.
[tex]\bold {{Percent Yield} = \frac{{Actual Yield}}{{Theoretical Yield}} \times 100 \%}[/tex]
Put the values in the formula,
[tex]\bold {{Percent Yield} = \dfrac{{26.5}}{54.9} \times 100 \%}\\\\\bold {{Percent Yield} = 48.3 \%}[/tex]
Therefore, the percentage yield of ammonia is 48.6 %.
