answer a and b answer a and b Determine the volume (in mL ) of

Determine the volume (in mL ) of water that needs to be added to 25.0 mL of a 0.250MNaBr to produce a 0.0195M solution. Assume the volumes are additive. A 0.600M solution of KCl needs to be prepared through dilution. A 2.00M stock solution will be added to a 0.250L volumetric flask and then water will be added to the 0.250L mark. Determine the volume (in mL ) of the 2.00M stock solution of KCl needed to produce this solution
