of a mixture of and requires of for complete reaction. Find the mole percentage of in the mixture. — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$CO_2 + 2NaOH \rightarrow Na_2CO_3 + H_2O$. <br>$\text{moles } NaOH = 0.1 \Rightarrow \text{moles } CO_2 = 0.05$. <br>$\text{moles } CO = 0.5 - 0.05 = 0.45$. <br>$\% CO = (0.45 / 0.5) \times 100 = 90\%$. [4, 25]
