Asolution of hno3 is standardized by reaction with pure sodium carbonate. 2h++na2co3⟶2na++h2o+co2 a volume of 25.15±0.05 ml of hno3 solution was required for complete reaction with 0.8395±0.0007 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.
