None of the above.
Add .00250 ml of stock to a volumetric flask, and dilute to 100. ml with water.
Add 2.50 ml of stock to a volumetric flask, and dilute to 100. ml with water.
Add 7.50 ml of stock to a volumetric flask, and dilute to 100. ml with water.


Remember that your stock is 2 M
Question Explanation:
Recall that M1V1=M2V2 (e.g. big M is for molarity and 1 and 2 are the solution volumes before and after dilution)
