Suppose that, from measurements in a microscope, you determine that a certain layer of graphene covers an area of 2.70μm2. convert this to square meters.

2.70 × 10 ⁻¹² m²

Explanation:

Graphene is the allotrope of the carbon in which there is a single layer of the atoms in the 2-D hexagonal lattice. In the lattice, one atom forms each of the vertex.

Given that the area covered by the layer of the graphene = 2.70 μm²

To convert this area into m²

Firstly,

1 μm = 10 ⁻⁶ m

So,

1 μm² = 10 ⁻¹² m²

The area into square meter = 2.70 × 10 ⁻¹² m²
