Solve the following 1) A solution is made by adding 24.8 mL of concentrated nitric acid (70.4 wt%, density 1.42 g/mL) to some water in a volumetric flask, and then adding water to the mark to make exactly 200 mL of solution. Calculate the concentration of this solution in molarity. 2) A 72.0 mL aliquot of a 1.50 M solution is diluted to a total volume of 288 mL. A 144 mL portion of that solution is diluted by adding...

The percentage by weight of nitric acid, HNO3, in a sample of concentrated nitric acid is to be determined. Initially a NaOH solution was standardized by titration with a sample of potassium hydrogen phthalate, KHC8H4O4, a monoprotic acid often used as a primary standard. A sample of pure KHC8H4O4 weighing 1.518 grams was dissolved in water and titrated with the NaOH solution. To reach the equivalence point, 26.90 millilitres of base was required. Calculate the molarity of the NaOH solution....
