PLEASE HELP WITH FIRST PART. NEED CORRECT SIG FIGS. SECOND PART IS CORRECT AS SEEN BELOW.

A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H+ + NaCO3 2 Na+ + H2O + CO2 A volume of 29.24 + 0.06 mL of HNO2 solution was required for complete reaction with 0.8846 + 0.0008 g of Na, CO3, (FM 105.988 + 0.001 g/mol). Find the molarity of the HNO2 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. 0.5709 0.001 It M [HNO3] = M Incorrect
