A solution of HNO 3 is standardized by reaction with pure sodium carbonate. 2 H + + Na 2 CO 3 ⟶ 2 Na + + H 2 O + CO 2 A volume of 26.66 ± 0.06 mL of HNO 3 solution was required for complete reaction with 0.9479 ± 0.0007 g of Na 2 CO 3 , (FM 105.988 ± 0.001 g/mol ). Find the molarity of the HNO 3 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.
