A solution of HNO, is standardized by reaction with pure sodium carbonate. 2H+ + NaCO, 2 Na+ + HO + CO A volume of 23.28 0.05 mL of HNO, solution was required for complete reaction with 0.8463 +0.0008 g of Na,CO,, (FM 105.9880.001 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.
