Correct me if Im wrong, But isnt the last one in the equation. 9g x 1/8 x -572/2 = -143. I just used my calculator with your equation. But when I followed your verbal explanation, you said 9 divided by 18 is half, and half of -572 is -286 KJm but shouldn't that not apply cause since you are doing a mole fraction calculation?
Should last problem be divided by two again? You said one half (from the 9/18)times -572, but what about the 2 ....
you are right.
