Stan is trying to determine the identity of his unknown sample using the density chart. Stan really believes that his sample is made of aluminum. He measures the mass of the sample and finds it to be 30 g. He measures the volume of his sample and finds it to be 11.11 cm3. Is Stan correct in thinking his sample is aluminum?
No, his samples is actually lead.
Yes, Stan has correctly identified his sample as aluminum.
No, his sample is actually zinc.
No, his sample is actually iron.
