You need to make a buffer by dissolving benzoic acid and sodium benzoate in
water. What is the mass of benzoic acid that you would weigh out, in mg, to
create 50 mL of a buffer at pH = 4.7 that will change pH no more than 0.10 units
with the addition of 0.001 moles of acid or base?
Enter just the answer without the units (mg) - just the number will do!
