Determine the concentration of the following dye standard made by a student who pipettes out 2.50 mL of a 0.250 M stock solution and transfers it into a volumetric flask and dilutes the dye to a final volume of 100.0 mL with DI water.

Concentration of dye in diluted solution is 0.00625 M

Explanation:

The given problem can be solved by using laws of dilution

According to laws of dilution-  

where and are initial and final concentration respectively

          and are initial and final volume respectively

Here, , and

So,

or,

or,

So, concentration of dye in diluted solution is 0.00625 M
