Carbon

[FISMAQUIM]

In 1996, the Nobel Prize in Chemistry was awarded to scientists who discovered a molecule in the form of a soccer ball,
called fullerene (C60). Besides this substance, graphite and diamond are also made of carbon. The densities of these substances,
not necessarily in the order presented, are: 3,5; 1,7 and 2,3 g/cm³. Based on the average distances between carbon atoms,
choose the appropriate density and calculate the mass, in grams, of a sphere of 2 cm diameter fullerene.

Data:
Mean distance between carbon atoms in nanometers (10^9 m)
diamond ...................... 0,178
fullerene .................... 0,226
graphite ..................... 0,207

Sphere Volume
V = (4πr³) / 3
