Identifying Acids and Bases

Q. You perform two titrations using the same standardized solution of base. You find that 0.500 g of Acid B requires twice as much base to titrate than 0.500 g of Acid A. If the molar mass of acid A and B are the same, what can you conclude about the acids? Acid A is monoprotic or diprotic? and Acid B is mono or di?
