If a student has 100.0 mL of a 0.100 M solution of propanoic acid and 100.0 mL of a 0.0850 M solution of sodium propanoate, the volume of propanoic acid solution he will have to mix with the sodium propanoate solution to prepare 85.0 mL of a buffer solution with a pH of 5.8 would be: (the pka for propanoic acid is 4.87) Show steps please

About two centuries ago, Benjamin Franklin showed that 1teaspoon of oil would cover about 0.5 acre of still water. If you know that 1.0 x 104 m2= 2.47 acres and that there is approximately 5 cm3 in a teaspoon, what is the thickness of the 0.5-acre layer of oil? How might this thickness be related to the sizes of molecules?
