Error in 6B.5 e)?

Postby Daniel_Frees_1L » Fri Dec 07, 2018 11:28 pm

I've gotten the same answer for 6B.5e) over and over and I'm convinced im doing the problem right. mg/L --> dimensional analysis to mol/L. OH- Molarity is the same because strong base. -log(M OH-) = -log(0.009714) = 2.012 = pOH. pH = 11.998. Does the answer key have a typo, or am I missing something?
