Calculate the molar concentration of the malonic acid if 38.17 mL of 0.315 M potassium hy-
droxide was required to neutralize 25.0 mL of malonic acid to a phenolphthalein end point.
b.
C.
Calculate the mass percent concentration of malonic acid using the molar concentration cal-
culated in part b and assuming the density of the solution is 1.01 g/mL.
