How to decrease the concentration of a solution?
This means that you can decrease the concentration of a solution by increasing its total volume while keeping the number of moles of solute constant. To increase the total volume of the solution, you would add solvent, which in this case is pure water.
What is the most important thing to remember about dilutions?
The most important thing to remember about dilutions is that the number of moles of solute must remain constant, i.e. the diluted solution will have the same number of solute as the sample of concentrated solution. As you know, the molarity of a solution tells you how many moles of solute you get per liter of solution.
