The boiling point of a water solution that is 1.5m NaCl
« on: March 23, 2008, 11:30:04 PM »
Please check the problem below. Thank you very, very much.
What is the boiling point of a water solution that is 1.5m NaCl?
My solution: 0.512 x 1.5 = 0.768 degrees C + 100 = 100.768 degrees C

Is this correct? Thank you.

Dear Oceanmd;

The Answer in your third identical Question is ok.   – And that’s also the correct argumentation!
BUT I don’t know how long your third identical Question will survive!!

You forgot!!:
And please read:  "Forum Rules” (3.)


Good Luck!

Argos,

The correct answer, which is boiling point elevation, should be 1.536 degrees C
When we add 100 degrees, which gives us 101.536, is the boiling point of the solution.
So the correct answer for this problem is 1.536 degrees C

Is this correct? Thank you

Dear Oceanmd;

As I told you already:  The Answer is ok!

But the Argumentation you did is also correct, and is at least of the same Importance!
