hi is a sturdy acid so it is going to dissociate thoroughly to form H+ and that i-. We first ought to calculate the style of moles of hi interior the answer. The molar mass of hi is 127.91g/mol, and we've 15g of it. 15g / 127.91g/mol = .1173 moles of hi in view that all of us be attentive to that hi is a sturdy acid then the style of moles of H+ is the comparable by way of fact the style of moles hi extra. Now we ought to calculate the concentration of H+. we've .1173mol H+ and a couple of.5L of answer: .1173 / 2.5L = .04691M Now what we've the concentration of H+ we are able to calculate pH: pH = -log[H+] pH = -log[.04691] pH = a million.33 And, now pOH: 14 = pH + pOH pOH = 14 - pH pOH = 14 - a million.33 pOH = 12.sixty seven

pH = 14 - pOH
pH = 14 - 3.68 = 10.32 ...
...and if you took the time to open a book, you could have found it quicker than the time it took to create this request.

These questions are a doddle - they're easy and you shouldn't be asking them unless you REALLY don't know.
14 - pOH = pH

Just subtract from 14.0 - so the answer is 10.32.
