When you heat 0.80g of copper carbonate and you weigh it after cooling how come the mass didn't change?

Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
