Question
You will need the following equations to help with this assignment:
n =
Mr
vol
pH = -log1o [H3O*1
pKa = -log1o Ka
[A]
pH = pKa+ logi0
[HA]
HA]
pH = pKa - logio
[A]
Remember that, to find the molecular mass of a molecule, you add
the molecular weights of all the components in the molecule.

I've used the buffer in question 4 and need to modify the last 250
mL so that it has a total osmotic concentration of 220 mM. How
much NaCl should I add to get this solution?
