Answer:
25%.
Explanation:
The following data were obtained from the question:
Experimental yield = 30 g
Actual yield = 40 g
Percentage error =..?
Thus, we can calculate the percentage error as follow:
Percentage error = |Experimental – Actual | / Actual × 100
Percentage error = |30 – 40|/40 × 100
Percentage error = 10/40 × 100
Percentage error = 25 %
Therefore, the percentage error in calculating the yield is 25%
