The recipe of carbonate buffer is as follows: 15mM sodium carbonate Na2CO3 35mM sodium bicarbonate NaHCO3 3.1mM sodium azide NaN3 (poisonous) You want to make 500mL of this buffer for your upcoming experiments. However, you don’t have enough stock solution of each to make this buffer. Instead of preparing more of each stock you decide to just weight out and mix crystals/powder of each with water. Show your calculations on how much crystals (in grams) of each you should weight out. [Atomic Mass: Na – 23; C – 12; N – 14; O – 16]
