A student measures 0.2452 g of a monoprotic solid acid, and dissolves the solid in water to make 100.0 mL of solution. The entire solution is titrated to a phenolphthalein endpoint with 45.09 mL of 0.1752 M KOH.
a) What is the molarity of the acid solution?
b) What is the molar mass of the solid acid?
