Answer:
2.3 M
Explanation:
First we calculate the final volume of the solution:
- Final Volume = 200 mL + 700 mL
With the final volume we can use a <em>dilution factor</em> to c<u>alculate the concentration of the diluted solution</u>:
- Original Concentration * Initial Volume / Final Volume = Final Concentration
- 3 M * 700 mL / 900 mL = 2.3 M
