Answer:
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
