A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2 H+ + Na₂CO3 → 2Na+ + H₂O + CO₂ A volume of 29.40 ± 0.06 mL of HNO3 solution was required for complete reaction with 0.9408 ± 0.0009 g of Na₂CO3, (FM 105.988 ± 0.001 g/mol). Find the molarity of the HNO3 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] = M + M It
