bo A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H + Na2CO3 2 Na+ + H2O + CO₂ A volume of 23.78 ± 0.05 mL of HNO3 solution was required for complete reaction with 0.9890 ± 0.0008 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. 0.785 0.0066 [HNO3] = M ± M Correct Answer Incorrect Answer
