Question

Trina conducted an experiment to determine the average amount of salt in 1 liter of ocean water by allowing the water to evaporate and measuring the remaining salt.

Her results are shown below.
Trial Salt
1 13.5 g
2 13.3 g
3 14.4 g
4 11.9 g
What is the mean weight of the salt precipitate?
13.5 g
13.1 g
13.3 g
53.1 g

Answer 7

does anyone know the answer?

Answer 8

In order to find the mean of a table you would add up the trial data and then divide it by how many trials you conducted...

Answer 9

If the data values are the weight of the salt after evaporation, I assume you can get the mean by adding the 4 values and dividing that sum by 4.

Answer 10

13.3 g is the closest to 13.275 which is the average of the 4 posted data points.

If this problem is from Chemistry, then you may need to reconsider the answer because of the evaporated water and salt precipate aspect of the problem.
