The dihydrogen phosphate/hydrogen phosphate buffer system studied above is present primarily in the red blood cells. Another buffer system found in your blood is the bicarbonate system. We will look

at that system now. Each pair of students would have prepared 250 mL of 0.0100 M sodium hydrogen carbonate. 1. How many moles of sodium hydrogen carbonate are needed to prepare this solution? 2. What is the formula weight of sodium hydrogen carbonate? 3.How many grams of sodium hydrogen carbonate are needed to prepare this solution?
