a. A 250.0-mL solution of sodium hydroxide was prepared by dissolving pure NaOH(s) in deionized water. It required 21.37 mL of 0.1127 M sulfuric acid to completely neutralize 39.29 mL of this sodium hydroxide solution. Calculate the mass, in units of g, of NaOH(s) that was dissolved to make the 250.0-mL solution. Enter your answer in decimal notation using 3 significant figures; i.e., enter 0.03478 as 0.0348 b. In an experiment, 23.24 mL of 0.235 mM silver nitrate are mixed with 9.12 Ml of 0.205 mM sodium phosphate. Assuming 100% yield, what is the concentration, in units of μM, of phosphate in the solution. Assume that the volume of the solid formed is negligible. Enter your answer in decimal notation using 3 significant figures; i.e. enter 2.579 as 2.58.
