Determine the total distance
This is calculated by summing up the distance in each segment.
Answer:
72.3%
Explanation:
The following data were obtained from the question:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.?
Percentage yield of a reaction can simply be obtained by dividing the actual yield by the theoretical yield multiplied by 100. This is illustrated below:
Percentage yield = Actual yield /Theoretical yield × 100
Thus, we can obtain the percentage yield of MgO as follow:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.? Percentage yield = Actual yield /Theoretical yield × 100
Percentage yield = 2.48/3.43 × 100
Percentage yield = 72.3%
Therefore, the percentage yield of MgO is 72.3%.
B a biotic factor is something living that affects the population of an organism
Answer:
88%.
Explanation:
The percentage yield of lead sulfate in this experiment is 88% if 2.53 is divided by 2.85 and multiply by 100. The percentage yield can be calculated when the experimental yield is divided by theoretical yield and then multiply by 100. The percentage yield tells us about the actual yield that is gained in the end of experiment which is lower than theoretical yield.
