So, I don't understand how to calculate concentration for solutions that have been diluted twice. You have W mL of a solution with concentration M. You dilute it to a final volume of X mL.You then pour it out until you're left with Y mL of that diluted solution. Then you dilute what's left to a final volume of Z mL.What's the formula for the final concentration of the solution?
