A student performs a standardization titration experiment for
NaOH with benzoic acid. They dissolve approximately 1 +/- 0.2 g of
NaOH in 290. mL of water. Separately 0.200 g of benzoic acid is
dissolved in 16.0 mL of water. If 16.0 mL of the NaOH solution is
required to reach the endpoint with the entire solution of benzoic
acid, what is the exact concentration (M) of the NaOH?
