Answer 2

Mf = MiVi / Vf

Step-by-step 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
