Homework Help: Chemistry

Posted by Emma on Thursday, June 24, 2010 at 3:42am.

Prepare a 0.0200 mM dye solution at low pH by dilution 0.40 ml of the stock 0.100 mM chemical X into the appropriate volume of 2.5 M HCl.

What is the amount of HCL required for dilution, the final concentration of HCl in the solution, and the pH?

I know there's the MV = MV, but I'm not sure how to begin to solve this. The 2.5 M HCl throws me off since there's two concentrations now (2.5 and the .02)
