Question 34

Copper carbonate breaks down on heating according to the equation:

$CuCO3→CuO+CO2\text{CuCO}_3 \rightarrow \text{CuO} + \text{CO}_2$

A sample containing 2.47 g of copper carbonate is heated until it has completely decomposed.

The relative formula mass ( $M_r$ ) of copper carbonate is 123.5.

At room temperature and pressure (rtp), one mole of any gas occupies 24 dm³.

Calculate the volume of carbon dioxide given off, measured at rtp. Give your answer in $cm3\text{cm}^3$ .
