A student investigated the stomatal density on the lower epidermis of Eucalyptus leaves. They used a light microscope to count the number of stomata in five circular fields of view.
The diameter of each circular field of view was 400 μm400\text{ }\mu\text{m}400 μm.
The number of stomata recorded in the five fields of view were:
Calculate the mean stomatal density for these fields of view. Give your answer to 3 significant figures as the number of stomata per mm2\text{mm}^2mm2. Show your working.
