A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H^+ + Na2CO3 ------> 2Na^+ + H2O + CO2

A volume of 28.28+-0.05 mL of HNO3 solution was required for complete reaction with 0.8711+-0.0007g of Na2CO3 (FM 105.988+-0.001). Find the molarity of the HNO3 and its absolute uncertainty with correct significant figures.

[HNO3] = __________M +- __________ M
