Suppose that, from measurements in a microscope, you determine that a certain layer of graphene covers an area of 1.80um2. Convert this to square meters.
Express the area in square meters to three significant figures.
Given data
Graphene has a layer of thickness=1.80 µm2
Area
...1.80um2 if one um is equal to 10'm then um2 is equa to 10 x 10 m2 10-12 m2 final area 1.80m2 2 = 1.80 x1012
