you have 20ml of an aqueous solution of 0.2M NaOH. if you add distilled water to this solution until you have 200ml , what will be the concentration? How many times did you dilute it?
Answered by bobpursley
it is diluted 10 times, so .02M. You added one part original, nine parts water.
Answered by Solly
The concentration is 0.02M then the solution is diluted 10 times by adding 180ml of distilled water
