Question
**Match the following quantities for $0.1 \text{ mole}$ of $Na_2CO_3$:** <br><br>**Column I:** <br>(A) Mass of sample <br>(B) Moles of $Na^+$ ions <br>(C) Moles of $O$ atoms <br>(D) Total moles of ions <br><br>**Column II:** <br>(P) $0.2$ <br>(Q) $10.6 \text{ g}$ <br>(R) $0.3$ <br>(S) $0.3$
Answer: (A) $\RIGHTARROW$ Q <BR>(B) $\RIGHTARROW$ P <BR>(C) $\RIGHTARROW$ R <BR>(D) $\RIGHTARROW$ S
💡 Solution & Explanation
**(A)** $\text{Mass} = 0.1 \times 106 = 10.6 \text{ g}$ (Q). <br>**(B)** $\text{moles } Na^+ = 2 \times 0.1 = 0.2$ (P). <br>**(C)** $\text{moles } O = 3 \times 0.1 = 0.3$ (R). <br>**(D)** $\text{Total ions} = (2 \text{ Na} + 1 \text{ CO}_3) \times 0.1 = 0.3$ (S).
