Part 1: Calculations Involving Solution Concentration Your problems will be given here and should be worked on paper and written neatly. (1) What mass of sodium hydroxide would be required to prepare 300mL of 6MNaOH ? (2) What mass of sodium hydroxide would be required to prepare 500mL of 0.10MNaOH ? (3) (a) Is it possible to make a sodium hydroxide solution of exact concentration by weighing the solute on an analytical balance, dissolving it in water and accurately diluting to the final desired volume? Explain your answer. (b) Discuss the relative accuracy of the concentration of a solution made by first making 6M NaOH and diluting that to 0,10MNaOH vs making the 0.10MNaOH directly by weighing the solute. (4) (a) What volume of 12MHCl solution would be required to prepare 250mL of 4MHCl ? (b) What volume of 4MHCl solution would be required to prepare 100mL of 0.10MHCl ? (5) Organic acids such as potassium hydrogen phthalate (KHP molecular formula KC8H6O2) are often used as primary standards to determine the exact concentration of a solution of strong base. If a 0.4162g sample of KHP required 27.82mL of NaOH solution to reach the equivalence point, what is the molar concentration of the sodium hydroxide solution
