c1v1 = c2v2
1.0M x v1 mL = 0.25M x 100 mL
v1 = mL of the 1.0 M stuff. Add to 100 mL volumetric flask and make to the mark with distilled water. Mix thoroughly.
You have a 1.0 M stock solution of H2SO4 in a large flask. You need to dilute this to make a 0.25M solution of H2SO4 for an experiment. If you need exactly 100.0mL of the diluted solution, how would you make the diluted solution?
