Using the food dye to interact and perform each dilution the values of cf , vf , and vi is mathematically given as
Generally, the equation for the reaction is mathematically given as
m1v1=m2v2
Therefore
[tex]m2=\frac{32*1}{40}[/tex]
m2=cf=8.0um
Therefore
[tex]Vf=\frac{40*1}{20}[/tex]
Vf=2.0mL
In conclusion, The initial volume
[tex]vi=\frac{2*8}{8}[/tex]
vi=2.0mL
