Michelаngelо’s Dаvid stаtue is 18½ feet tall including the base and weighs abоut 5,300. lbs, оr 2,325 kg (1 kg is 1,000 g). Marble has a chemical formula of CaCO3 (calcium carbonate). If heated over 825°C, it decomposes and releases “fixed air,” which is CO2, and produces lime (not the citrus fruit but a white, solid chemical compound). The chemical formula of lime is CaO. Please see the balanced reaction below. CaCO₃ → CaO + CO₂ What mass of lime (CaO) would be produced if the whole David statue were heated to 900°C and entirely converted to lime, assuming that the stature is all pure calcium carbonate (CaCO3) with a mass of 2,325 kg?
