Answer:
82.45%
Explanation:
Data obtained from the question include:
Experimental yield = 15.5g
Theoretical yield = 18.8g
Percentage yield =?
The percentage yield of calcium carbonate can be obtained as follow:
%yield = Experimental yield/Theoretical yield x100
%yield = 15.5/18.8 x 100
%yield = 82.45%
Therefore, the percentage yield of calcium carbonate is 82.45%
