PLEASE HELP ME !!!!

A 500.0 mL stock solution of copper sulfate (1.00 x 10-4 M) was prepared using 0.1 M sulfuric acid to dissolve the solid.
The above stock solution was then used to prepare three standard solutions with the following concentrations: 1.00 x 10-6 M, 5.00 x 10-6 M and 1.00 x 10-5 M (final volume of each was 50.0 mL). In addition to the stock solution, each standard solution contained the following:
• 25 mL of sodium acetate (0.4 M)
• 0.1 M sulfuric acid to top up to the final volume of each standard

What is Cava ?

nvm then

anonymous · Answer

How do I go about preparing the solutions from the stock solution ?

wolfe8 · Answer

Use $$m _{1}v _{1}=m _{2}v _{2}$$

anonymous · Answer

I did but for some reason since it says that it also includes 2 other solutions that add to the volume it feels like it is wrong. Or does that not matter ?
