Answer to Problem 8.68EP

The volume of water should be added to yield the given solution is 175 mL.

Explanation of Solution

Given information:

Volume of solution = 25.0 mL

Initial concentration = 1.00 M

Required concentration = 0.125 M

Final volume of solution = ?

Apply dilution equation to calculate the volume of water should be added to yield the given solution,

Cs×Vs=Cd×Vdrearrangetheaboveequation,Vd=dilutedvolume=Vs×CsCd=25.0mL×1.00M0.125M=200mL

Now subtract the original volume (Vd) from the final volume (Vs)

Volumeofwateradded=Vd-Vs=200mL-25.0mL=175mL

Therefore, the volume of water should be added to yield the given solution is 175 mL.

Answer to Problem 8.68EP

The volume of water should be added to yield the given solution is 395 mL.

Explanation of Solution

Given information:

Volume of solution = 5.00 mL

Initial concentration = 10.0 M

Required concentration = 0.125 M

Final volume of solution = ?

Apply dilution equation to calculate the volume of water should be added to yield the given solution,

Cs×Vs=Cd×Vdrearrangetheaboveequation,Vd=dilutedvolume=Vs×CsCd=5.00mL×10.0M0.125M=400mL

Now subtract the original volume (Vd) from the final volume (Vs)

Volumeofwateradded=Vd-Vs=400mL-5mL=395mL

Therefore, the volume of water should be added to yield the given solution is 395 mL.

Answer to Problem 8.68EP

The volume of water should be added to yield the given solution is 47500 mL.

Explanation of Solution

Given information:

Volume of solution = 2500 mL

Initial concentration = 2.50 M

Required concentration = 0.125 M

Final volume of solution = ?

Apply dilution equation to calculate the volume of water should be added to yield the given solution,

Cs×Vs=Cd×Vdrearrangetheaboveequation,Vd=dilutedvolume=Vs×CsCd=2500mL×2.50M0.125M=50000mL

Now subtract the original volume (Vd) from the final volume (Vs)

Volumeofwateradded=Vd-Vs=50000mL-2500mL=47500mL

Therefore, the volume of water should be added to yield the given solution is 47500 mL.

Answer to Problem 8.68EP

The volume of water should be added to yield the given solution is 3.0 mL.

Explanation of Solution

Given information:

Volume of solution = 75.0 mL

Initial concentration = 0.130 M

Required concentration = 0.125 M

Final volume of solution = ?

Apply dilution equation to calculate the volume of water should be added to yield the given solution,

Cs×Vs=Cd×Vdrearrangetheaboveequation,Vd=dilutedvolume=Vs×CsCd=75.0mL×0.130M0.125M=78mL

Now subtract the original volume (Vd) from the final volume (Vs)

Volumeofwateradded=Vd-Vs=78.0mL-75.0mL=3mL

Therefore, the volume of water should be added to yield the given solution is 3.0 mL.
