A solution of HNO3 is standardized by reaction with pure sodium carbonate:
2H^+ + Na_2CO_3 ---> 2Na^+ +H_2O + CO_2
A volume of 23.60 ± 0.05 mL of HNO3 solution was required for complete reaction with 0.9437 ± 0.0008 g of Na2CO3, (FM 105.988 ± 0.001). Find the molarity of the HNO3 and its absolute uncertainty.
[HNO_3] = ______ M +- ______ M
