There is 0.3998 g of bromophenol blue and brought it to 2L of distilled water. Then you took 5 mL of that stock solution and brought it to 100mL by adding 0.05M KHP. then to make solution A3, you took 16 mL of your solution and brought it to a total volume of 20mL. Calculate the total concentration of indicator in A3.
