The mass of oxygen gas evolved during the heating process is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The mass of oxygen gas evolved during the heating process is:
Answer: A
💡 Solution & Explanation
$\text{Mass loss} = \text{Initial mass} - \text{Residue mass} = 5.0 - 4.84 = 0.16\text{ g}$. This mass loss is entirely due to the evolved $O_2$.
