![**Question:**
What is the concentration of sodium ions in 0.285 M \( \text{Na}_2\text{CO}_3 \)?
**Answer Box:**
M
---
**Explanation:**
To solve this problem, we need to determine the concentration of sodium ions (\( \text{Na}^+ \)) in a solution of sodium carbonate (\( \text{Na}_2\text{CO}_3 \)).
**Step-by-step Solution:**
- \( \text{Na}_2\text{CO}_3 \) dissociates in water to form two sodium ions and one carbonate ion:
\[
\text{Na}_2\text{CO}_3 \rightarrow 2 \text{Na}^+ + \text{CO}_3^{2-}
\]
- Therefore, for every mole of \( \text{Na}_2\text{CO}_3 \), two moles of \( \text{Na}^+ \) are produced.
- Given the solution concentration is 0.285 M \( \text{Na}_2\text{CO}_3 \), the concentration of sodium ions is:
\[
2 \times 0.285 \, \text{M} = 0.570 \, \text{M}
\]
**Conclusion:**
The concentration of sodium ions \( (\text{Na}^+) \) in the solution is 0.570 M.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56c0d6f8-9f13-42b8-9b57-0cbb0f2f598f%2F201b5aaf-46b7-4532-a107-9729621ba73c%2Fmk8c5yo_processed.png&w=3840&q=75)

Transcribed Image Text:**Problem Statement:**
100.0 mL of a 0.710 M solution of KBr is diluted to 500.0 mL. What is the new concentration of the solution?
---
**Graph/Diagram Explanation:**
There is no graph or diagram, but there is a partially filled line with the label "M", indicating that the answer should be expressed in molarity (M).
