A solution of HNO, is standardized by reaction with pure sodium carbonate. 2 H+ + Na,coz 2 Na+ + H2O + CO2 A volume of 25.80 + 0.05 mL of HNO2 solution was required for complete reaction with 0.8836 + 0.0008 g of Na, CO3, (FM 105.988 + 0.001 g/mol). Find the molarity of the HNO, solution and its absolute uncertainty. Note: Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations. (HNO3) = 0.6463 M + 0.002 M Incorrect Incorrect
