A solution of HNO3 is standardized by reaction with pure sodium carbonate.

2H+ + Na2CO3 ------> 2Na+   + H2O +CO2

A volume of 25.82 ± 0.05 mL of HNO3 solution was required for complete reaction with 0.8759 ± 0.0007 g of Na2CO3, (FM 105.988 ± 0.001). Find the molarity of the HNO3 and its absolute uncertainty.
