Using the food dye to interact and perform each dilution the values of cf , vf , and vi  is mathematically given as

  • m2=cf=8.0um
  • Vf=2.0mL
  • vi=2.0mL

What are the values of cf , vf , and vi?

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
