Volume of at STP produced by the decomposition of 10g of pure is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
Volume of $CO_2$ at STP produced by the decomposition of 10g of $80\%$ pure $CaCO_3$ is:
Answer: A
💡 Solution & Explanation
Pure $CaCO_3 = 8 \text{ g} = 0.08 \text{ mol}$. $CaCO_3 \rightarrow CaO + CO_2$. 0.08 mol $CO_2$ is produced. $\text{Volume} = 0.08 \times 22.4 = 1.792 \text{ L}$.
