A chemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision here are the data she has been given by each plant
South fork 46.82L
Doheny 9.47L
New salem 0.377L
What average volume should the chemical engineer report? Be sure your answer has the correct number of significant digits in L?
To find the average volume, we need to add up all the volumes and then divide by the total number of plants.
Total volume = 46.82 L + 9.47 L + 0.377 L = 56.667 L
To determine the correct number of significant digits, we look at the least precise measurement, which is 0.377 L with three significant digits.
Therefore, the average volume should be reported as 56.7 L.
To find the average volume of the pollutant produced by the plants, you will need to calculate the mean.
Step 1: Add up the volumes of each plant.
46.82 L + 9.47 L + 0.377 L = 56.667 L
Step 2: Divide the total volume by the number of plants (in this case, 3):
56.667 L / 3 = 18.889 L
Step 3: Round the result to the correct number of significant digits. Since the least precise measurement has 3 significant digits (0.377 L), the final answer should also have 3 significant digits:
18.889 L rounded to 3 significant digits = 18.9 L
Therefore, the chemical engineer should report the average volume of the pollutant produced by the plants as 18.9 L.
