Iron is a strong, hard metal with a high melting point. It is magnetic, meaning it is attracted to magnets. Iron has a density of 7.88 g/cm³, which means it is much denser than water. These properties make iron ideal for making nails, girders, and machinery. Pure iron is actually quite soft — it is usually combined with carbon to make steel, which is much stronger.
Iron has a density of 7.88 g/cm³. Calculate the mass of an iron nail with a volume of 2 cm³.
