1. Prepare the NaOH solution by dissolving approximately 4g of solid NaOH in 200 mL of water. Calculate and record the approximate NaOH concentration (MW = 40.00).
2. To prepare the primary standard, first calculate and record the expected mass of benzoic acid required to react in stoichiometric proportion with 20 mL of the NaOH solution (MW = 122.12). Record this amount.
