Oh I was doing 1:2 ratio instead of 1:1... That is where I went wrong! When I recalculated it with 1:1 I got 0.066628 M
Thank you!
My biggest problem is knowing where to start. So I calculate the ionic strength then the activity coefficients. Then do I just "plug and chug"
Oh, ok! I was over thinking the problem!!! Plus a fever may not help with my problem solving abilities... Thank you!
That is what I was thinking. I just was not sure if firing the object made a difference.
I figured out what I was doing wrong! I have the right answer! Yay!
I am doing something wrong in my calculations. For ?M I have 0.24 My equation is: 2.8*10^(-18) = (3x)^3 * (x+0.24)
Thank you so much!!!
I figured it out. I had to use a ΔG° from a previous problem.
