A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2 H+ + Na2CO3 → 2Na+ + H2O + CO2. A volume of 26.66 ± 0.06 mL of HNO3 solution was required for complete reaction with 0.8500 ± 0.0007 g of Na2CO3 , (FM 105.988 ± 0.001 g/mol). Find the molarity of the HNO3 solution and its absolute uncertainty.

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
