The number of atoms in 0.1 mol of a triatomic gas is : () — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Number of atoms = $\text{moles} \times \text{atomicity} \times N_A$. For a triatomic gas, atomicity is 3. $\text{Atoms} = 0.1 \times 3 \times 6.022 \times 10^{23} = 1.806 \times 10^{23}$. [1]
