The rhombic Sis all converted to monoclinic S (density 1.96g/cm3) to get a volume of4.22cm3 monoclinic S. 8.28g of rhombic S (density 2.07g/cm3) occupies 4 cm3. Both allotropic forms of sulfur consist of discrete cyclic S8 molecules. Determine the numbers of moles of S8 molecules are in the sulfur sample where the molar mass of S= 32.1g so molar mass of S8 = 257g
