Suppose that, from measurements in a microscope, you determine that a certain layer of graphene covers an area of \( 1.70 \mu \mathrm{~m}^{2} \). Convert this to square meters. Express the area in square meters to three significant figures.

To convert from square micrometers to square meters, you can use the conversion factor where \(1 \mu m^2 = 1 \times 10^{-12} m^2\). Therefore, to convert \(1.70 \mu m^2\) to square meters, you would calculate: \[ 1.70 \mu m^2 \times 1 \times 10^{-12} m^2/\mu m^2 = 1.70 \times 10^{-12} m^2 \] Expressed to three significant figures, the area in square meters is: \[ \text{Area} = 1.70 \times 10^{-12} m^2 \]
