A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H^+ + Na_2 CO_3 rightarrow 2Na^+ + H_2O + CO_2 A volume of 27.29 plusminus 0.06 mL of HNO_3 solution was required for complete reaction with 0.9623 plusminus 0.0007 g of Na_2CO_3 (FM 105.988 plusminus 0.001). Find the molarity of the HNO_3 and its absolute uncertainty.
