Final answer:
To convert 7.8 x 10^0 cubic meters to cubic nanometers, multiply by 1 x 10^27 to get 7.8 x 10^27 cubic nanometers.
Step-by-step explanation:
The question asks for the conversion of an atom's volume from cubic meters (m³) to cubic nanometers (nm³). To perform this conversion, we use the relationship that 1 m³ is equivalent to 1 x 1027 nm³. Therefore, if an atom has a volume of 7.8 x 100 m³, we need to multiply this number by 1 x 1027 to find the corresponding volume in nm³.
Volume in nm³ = 7.8 x 100 m³ x 1027 nm³/m³ = 7.8 x 1027 nm³.
