1.You have 0.50L of a gold chloride solution. You add 0.50L to the solution creating 1.0L of solution with a concentration of 0.26M. What was the original concentration?
2.You dissolve 0.26 moles of Co(NO3)2 in 0.30L of water. The resulting concentration is 0.87M. For an experiment, you need a concentration of 0.30M. What volume of water is needed for this concentration to result?
3. You dissolve 0.50 moles of NiCl2 in 0.40L of water. The resulting concentration is 1.3M. You increase the water in the solution until you have 0.80L. What is the new concentration?
