A solution of KI in water is .25M. How much water must be added to 50mL of this solution to reduce the concentration to .10M? assume volumes are additive.----2. An isotonic saline is .89% NaCl (w/v). Suppose you wanted to make a liter of isotonic solution of NH4Cl. What weight of NH4Cl would you need?
please provide step by step onstructions with details.
1. Number of moles of KI present in 50 ml of 0.25M solution = 0.25*50/1000 = 0.0125
Suppose the final volume of ...
