You have an aqueous solution at 25°C with [OH-] = (2.748x10^-7) M. What is the pOH of this solution? (pOH is a unitless quantity.) NOTE: To use scientific notation for the concentration, D2L requires that the pOH be reported using scientific notation as well. I apologize for the awkward formatting. Note: Your answer is assumed to be reduced to the highest power possible.

questions. Be sure you explain your answers, so that we may all
learn from each other. Simply writing an answer as a single word
doesn't help your fellow classmates understand
why.
