How many moles of are produced by the thermal decomposition of of ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
How many moles of $CO_2$ are produced by the thermal decomposition of $10\text{ g}$ of $CaCO_3$?
Answer: 0.1
💡 Solution & Explanation
$\text{moles } CaCO_3 = 10 / 100 = 0.1\text{ mol}$. <br>Decomposition: $CaCO_3 \rightarrow CaO + CO_2$. <br>Stoichiometry is $1:1$, so $0.1\text{ mole } CO_2$ is produced.
