The substance is likely zinc. Zinc has a density close to 7.14 g/cm^3, so 273 g of zinc would displace about 38.2 ml of water (273 g ÷ 7.14 g/cm^3 = 38.2 cm^3 or ml). Since the displacement is 26 ml, it closely matches with the expected value for zinc, indicating that the substance is most likely zinc.
