The mass of the ash is less than the original 3000 grams of wood because during combustion, the wood reacts with oxygen in the air to produce gases such as carbon dioxide and water vapor, which are released into the atmosphere. While the law of conservation of mass states that mass cannot be created or destroyed, in this case, the mass of the burned wood is transformed into gaseous products that leave the system, resulting in less mass remaining as ash.
