Question 21

A sample of copper carbonate is heated until it decomposes completely.

CuCO3→CuO+CO2\text{CuCO}_3 \rightarrow \text{CuO} + \text{CO}_2CuCO3​→CuO+CO2​

The relative formula mass, MrM_rMr​, of copper carbonate is 124. The volume of one mole of any gas at room temperature and pressure is 24 dm3.

Calculate the volume of carbon dioxide produced at room temperature and pressure when 12.4 g of copper carbonate decomposes.
