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

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
