5I.27 in 7th edition

Postby paytonm1H » Fri Jan 18, 2019 7:40 pm

Hi all,
I am currently working through 5I.27 and keep getting 8.7119 or 0.0738 for x, but the answer key has 9.2 or 0.071 for x. I have the quadratic equation set up the same as the answer key but can't find any mistakes in my calculations. Has anyone else run into this problem?

I also ran into the same problem. However, using the value 0.07379 from my calculation, the equilibrium concentrations come out the same as those in the solutions manual. The discrepancy is taken care of by rounding and sig figs.
