We’re asked to determine how the molarity of a 0.50 M KBr solution changes when water is added to double its volume.
Recall that when we are adding water (or solvent) to a solution, we are diluting the solution.
When dealing with dilution we will use the following equation:
M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume
Calculate the Molarity of KBr when its volume is doubled.
How is the molarity of a 0.50 M KBr solution changed when water is added to double its volume?
