Which equation should you use to find the final
concentration?

Answer:
Mf = MiVi / Vf
Explanation:
To obtain the answer to the question given, let us obtain the equation for the final concentration.
This can be obtained from the dilution equation as shown below :
MiVi = MfVf
Mi is the initial concentration
Mf is the final concentration
Vi is the initial volume
Vf is the final volume.
Making Mf the subject of the above equation, we can obtain the equation which can be used to calculate the final concentration. This is illustrated below:
MiVi = MfVf
Divide both side by Vf
Mf = MiVi / Vf
Therefore, the equation which can be used to calculate the final concentration is Mf = MiVi / Vf
The first part to this question is:
What is the final volume? 150.0
the second part:
Which equation should you use to find the final concentration? 3rd option
The 3rd part:
What is the new concentration? 0.125 M NaCl
