So what does it mean to say that a solution of NaCl is .5 M?

anonymous · Answer

i dont know? @Mertsj

mertsj · Answer

It means there are .5 moles of NaCl in 1 liter of that solution

anonymous · Answer

Ok @Mertsj

mertsj · Answer

So if there are .5 moles in 1 liter, how many moles are in 5 liters?

mertsj · Answer

Heres the question @Mertsj

It says to give the answer in moles.  How many moles of NaCl are there in 1.87L of .500 M NaCl?

anonymous · Answer

mertsj · Answer

anonymous · Answer

0.935 @Mertsj

mertsj · Answer

So why don't you put that down for your answer and move on?

anonymous · Answer

because i asked you if that was the answer and you said you wernt sure

anonymous · Answer

0.935M is the answer then right? @Mertsj

mertsj · Answer

That's because I was trying to get you to read the question and answer the question it asked instead of depending on someone else to tell you the answer.

anonymous · Answer

ok sorry thanks for your help @Mertsj

mertsj · Answer

And no, the answer is NOT .935 M because that means .935 moles per liter.  The answer is .935 moles of NaCl in 1.87 liters of .500 M solution
