Question

A solution of sodium bicarbonate is prepared by adding 45.00 gof sodium bicarbonate to 1.00 L volumetric flask and addingdistilled water until it is quantity sufficient at 1 liter. What isthe concentraton of sodium bicarbonate in a. Milligrams per liter b. Molarity c. Normality d. Milligrams per liter as CaCO3 A solution of sodium bicarbonate is prepared by adding 45.00 gof sodium bicarbonate to 1.00 L volumetric flask and addingdistilled water until it is quantity sufficient at 1 liter. What isthe concentraton of sodium bicarbonate in a. Milligrams per liter b. Molarity c. Normality d. Milligrams per liter as CaCO3

Explanation / Answer

a) 45.00 g * 1 000mg/1 g = 4.50 *104 mg/L b) molarity = moles/L                  =45.00 g* 1 molNaHCO3        = 0.536mol/L                                        84.01 g NaHCO3 c)Normality = molarity * n, where n represent the # protonsexchange in the reaction Normality = molarity in this case d) Not sure what the question is
