Ask a qMolarity and absolute uncertainty A solution of HNO3 is standardized by reaction with pure sodium carbonate 2H+ + Na2CO3 -> 2Na+ + H2O + CO2 a volume of 25.54+/- 0.06 mL of HNO3 was required for complete reaction with 0.8784+or- 0.0008g of Na2CO3 (FM 105.988+or- 0.001). Find the molarity of the HNO3 and its absolute uncertainty
