What volume of is required to produce of from ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
What volume of $0.2 \text{ M } H_2SO_4$ is required to produce $3.4 \text{ g}$ of $H_2S$ from $FeS$?
Answer: A
💡 Solution & Explanation
$FeS + H_2SO_4 \rightarrow FeSO_4 + H_2S$. <br>$\text{Moles } H_2S = 3.4 / 34 = 0.1 \text{ mol}$. <br>$\text{Moles } H_2SO_4 \text{ required} = 0.1 \text{ mol}$. <br>$\text{Volume} = \text{moles} / \text{molarity} = 0.1 / 0.2 = 0.5 \text{ L} = 500 \text{ mL}$.
