A certain container contains 4.4 g of and 2.3 g of . The total number of atoms in the container is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Moles of $CO_2 = 4.4 / 44 = 0.1$. Atoms $= 0.1 \times 3 \times N_A = 0.3 N_A$. <br>Moles of $NO_2 = 2.3 / 46 = 0.05$. Atoms $= 0.05 \times 3 \times N_A = 0.15 N_A$. <br>Total atoms $= 0.3 N_A + 0.15 N_A = 0.45 N_A$. [1]
