The number of moles of hydroxide ions in of is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The number of moles of hydroxide ions in $0.3\text{ L}$ of $0.1\text{ M } Ba(OH)_2$ is:
Answer: B
💡 Solution & Explanation
$Ba(OH)_2 \rightarrow Ba^{2+} + 2OH^-$. <br>$\text{Moles of } Ba(OH)_2 = 0.3 \times 0.1 = 0.03\text{ mol}$. <br>$\text{Moles of } OH^- = 2 \times 0.03 = 0.06\text{ mol}$. [3, 4]
