500ml of an HTS/TS- buffer (pKa = 5.25) at pH 4 was prepared. Unfortunately, the student who had prepared the buffer forgot how many moles of HTS and TS- he had added. Although HTS does not fluoresce, TS- does fluoresce. (If = 1000CTS). The intensity of the fluorescence signal from the buffer is 10. How many moles of HTS and TS- were used to prepare 500ml of the pH 4 buffer?
