1.  It is strange to me to see this post with no question.


2.  So, I must to guess what is the question.


3.  Sure, I am smart enough to guess the question. It is 

    "Find the new concentration".


4.  The answer is: new concentration =  = 2.45 M (which means 2.45 Moles per Liter).


5.  The solution by "josgarithmetic" is a) WRONG,   and   b) IRRELEVANT.


6.  Next time accompany your post with the question, if you want to get a qualified answer.
