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

2H⁺ + Na₂CO₃ --> 2Na⁺ + H₂O + CO₂

A volume of 27.87 ± 0.06 mL of HNO3 solution was required for complete reaction with 0.8538 ± 0.0008 g of Na2CO3, (FM 105.988 ± 0.001). Find the molarity of the HNO3 and its absolute uncertainty. Express the absolute uncertainty with three significant figures.

A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H+ + Na2Co3 arrowto 2Na+ + H2O + CO2 A volume of 25.36+/- 0.06mL of HNO3 solution was required for complete reaction with 0.9572 +/- 0.0008 g of Na2CO3 (FM 105.988 +/- 0.001). Find the molarity of the HNO3 and its absolute uncertainty. HNO3= M +/- M (sig figs count for this) If you could show me step-by-step how to do this problem, that would be helpful.

Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) Part A: What volume of 2.75 M HCl in liters is needed to react completely (with nothing left over) with 0.750 L of 0.400 M Na2CO3? Part B: A 675-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 18.1 g CO2. What was the concentration of the HCl solution?

A solution is prepared by dissolving 11.6 g of a mixture of sodium carbonate and sodium bicarbonate in 1.00 L of water. A 300.0 cm3sample of the solution is then treated with excess HNO3 and boiled to remove all the dissolved gas. A total of 0.940 L of dry CO2 is collected at 298 K and 0.972 atm. 1. Find the molarity of the carbonate in the solution. 2. Find the molarity of the bicarbonate in the solution.
