Question
A solution of HNO, is standardized by reaction with pure sodium carbonate.
2 H* + Na, CO, → 2 Na* + H, 0 + CO,
A volume of 26.62 ± 0.06 mL of HNO, solution was required for complete reaction with 0.8249 + 0.0008 g of Na,CO3,
(FM
105.988 + 0.001 g/mol). Find the molarity of the HNO, solution and its absolute uncertainty.
Note: Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of
your calculations.
