Calcium carbonate, when heated, decomposes according to the following chemical equation:
\(\ce{CaCO3 -> CaO(s) + CO2(g) }\)
60.0 grams of calcium carbonate is heated and the calcium oxide residue produced is weighed and recorded in the table below.
\begin{array} {|l|c|}
\hline
\rule{0pt}{2.5ex} \text{Mass of}\ \ce{CaCO3} \rule[-1ex]{0pt}{0pt} & \text{60.0 grams} \\
\hline
\rule{0pt}{2.5ex} \text{Mass of}\ \ce{CaO} \rule[-1ex]{0pt}{0pt} & \text{33.6 grams} \\
\hline
\end{array}
Determine the percentage of carbon dioxide, by weight, released from the calcium carbonate during this process. (2 marks)
