Answer to Question #117666 in General Chemistry for Ayda Ghodrati

Question

4. 45.0 mL of a solution of NaOH is diluted by adding 250.0 mL of water to produce a new molarity of 0.0500 M. Calculate the molarity of the base.

5. A 0.125 M solution is concentrated by evaporation to a reduced final volume of 100.0 mL and a molarity of. 0.150 M. Calculate the original volume.

6. 850.0 mL of 0.280 M KOH solution is diluted to a final volume of 1000.0 mL, calculate the new concentration.

7. 95.0 mL of a solution of NaOH is diluted to a final volume of 135 mL and the new molarity is 0.0500 M. Calculate the original molarity of the base.

8. What is the concentration of the resulting NaOH solution when you mix 125.0 mL of 0.250M NaOH with 200.0 mL of 0.175M NaOH?

9. 75.0 mL of 0.200M Al2O3 are added to 25.0mL of 0.800M Li2O. Calculate the resulting concentration of each ion in in the mi
