FISMAQUIM Posted March 5, 2018 Posted March 5, 2018 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
