1. Calculate the normality of 0.321 g sodium carbonate (106.0 g/mol) when it is mixed in a 250 mL solution.
2. What is the normality of 0.0521 M H3PO4?
3. A12.5-mL portion of a base solution of an element from group 2A is diluted to 500 mL; the resulting concentration of this solution is determined to be 0.125 M. What is the normality of the original solution.
4. A sample of USP-grade citric acid (H3C6H5O7, three titratable protons) is analyzed by titrating with 0.1087 M NaOH. A 0.2678-g sample requires 38.31 mL of the titrant for titration.
A. What is the normality of the titrant?
B. What is the stoichiometric relationship between the analyte and the titrant?
C. How many moles of the titrant were consumed to react with the analyte?
