We can can measure the concentration of HCl solution (a procedure called standardizing the solution) by reaction with pure sodium carbonate: 2H+ + Na2CO3à2Na+ + H2O + CO2. A volume of 27.35±0.04 mL of HCl solution was required for complete reaction with 0.9674 ±0.0009 g of Na2CO3 (FM 105.988 ± 0.001). Find the molarity of the HCl and its absolute uncertainty.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
