A dilute solution of unknown weak acid was titrated to the endpoint with 28.62mL of 0.1804 M NaOH. The titrated solution was evaporated to dryness as well as the sodium salt of the acid was found to weigh 0.223 grams. Presume the acid had a single titratable proton. Explain what is the molar mass of the acid?
