If you make a .5L solution containing .5 mol of KCL, what is the molarity of the solution?
A. 0.1 M
B. 0.2 M
C. 1 M
D. 2 M
E. 10M
Answer is 1 M. but i picked 2 M because of the dissociation of KCL. Can anyone tell me when we consider this. I know we take into account in boiling point and freezing point depression. but i thought it should apply here also. 0.5 mol of KCL would mean .5 mole K and .5 mole Cl. so total of 1 mole. so 1mole/.5L = 2M !!!!
this is frustrating. any help would be greatly appreciated.
