Final answer:

The mean is calculated by adding the measurements and dividing by the count of measurements to obtain an average value.


Explanation:

Mean: To find the mean we add together the individual measurements and divide by the number of measurements. The sum of the 10 concentrations is 1405. Dividing the sum by 10 gives the mean as 140.5, or 1.40 × 10² mmol/L.
