Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of a 0.5972 g sample of powdered limestone was measured by suspending the powder in water, adding 25.00 mL of 0.508 molar hydrochloric acid, and heating to dissolve the solid and dispel carbon dioxide gas. The excess acid required 36.29 mL of 0.1064 molar sodium hydroxide for complete titration to a phenolphthalein end point. What is the weight percent of calcite in the limestone?
