I don't understand what calculations I would have made to create
the buffer solution from Part D of the lab. I understood the
procedures I took to create the solution but when the report asks
to show the calculations used to prepare the buffer solution I am
not sure other than mixing the volumes indicated in the procedures
section.
Thank you
