We can can measure the concentration of HCl solution (a procedure called standardizing the solution) by reaction with pure sodium carbonate: 2H+ + Na2CO3à 2Na+ + 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.
