How many grams of are produced on heating of ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
How many grams of $CO_2$ are produced on heating $50 \text{ g}$ of $CaCO_3$?
Answer: 22
💡 Solution & Explanation
$\text{moles } CaCO_3 = 50 / 100 = 0.5 \text{ mol}$. <br>Decomposition gives $0.5 \text{ mol } CO_2$. <br>$\text{Mass } CO_2 = 0.5 \times 44 = 22 \text{ g}$.
