Based on the concept of equivalent volume, what is the exact volume occupied by exactly of Oxygen ga — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
Based on the concept of equivalent volume, what is the exact volume occupied by exactly $1\text{ gram equivalent}$ of Oxygen gas ($O_2$) at Standard Temperature and Pressure (STP)?
💡 Solution & Explanation
Step 1: Understand the definition of gram equivalent volume. It is the volume occupied by one equivalent weight of a gas at STP. Step 2: Determine the equivalent weight of Oxygen. The equivalent weight of atomic oxygen is $8\text{ g}$. Step 3: Relate mass to volume at STP. We know that $1\text{ mole}$ of $O_2$ gas ($32\text{ g}$) occupies exactly $22.4\text{ L}$ at STP. Step 4: Calculate the volume for $8\text{ g}$. Volume = $\left(\frac{22.4\text{ L}}{32\text{ g}}\right) \times 8\text{ g} = 5.6\text{ L}$.
