What's the concentration of [OH-] ions in a solution with a pH of 11.36? (This is a
bit of a trick problem! Remember that to
find [OH-] you need a pOH value. So first
find the pOH and then the [OH-].)
4.37x10-12M

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
