Aluminum Oxide Al2O3 is used in the purification of water. It is an electrical insulator also usedas a substrate for integrated circuits. For a cylindrical shape of 1 um diameter and 30 cmlength, what is the number of Al2O3 molecules? Given the density of Al2O3 is 3.97 g/cm³, MAI= 26.98 g/mole, Mo = 16 g/mole and Avogadro's number NA= 6.023 x 1023 atoms/mole ormolecules/mole.XO2.21 x 1010 moleculesO 1.11 x 1010 moleculesO 0.55 x 1010 moleculesO1.66 x 1010 molecules

Given that d=1 um =10-6 m l =30 cm =0.3 m NA =6.023 ×1023ρ=3.97 gcm3=3.97 × 106 gm3
