Question
**Match the following samples with their corresponding mole counts:** <br><br>**Column I:** <br>(A) $44\text{ g } CO_2$ <br>(B) $32\text{ g } CH_4$ <br>(C) $48\text{ g } O_3$ <br>(D) $2\text{ g } H_2$ <br><br>**Column II:** <br>(P) $1 \text{ mole}$ <br>(Q) $2 \text{ moles}$ <br>(R) $N_A \text{ molecules}$ <br>(S) $2 N_A \text{ molecules}$
💡 Solution & Explanation
**(A)** $44/44 = 1 \text{ mol}$ (P) and $N_A$ molecules (R). <br>**(B)** $32/16 = 2 \text{ mol}$ (Q) and $2 N_A$ molecules (S). <br>**(C)** $48/48 = 1 \text{ mol}$ (P) and $N_A$ molecules (R). <br>**(D)** $2/2 = 1 \text{ mol}$ (P) and $N_A$ molecules (R).
