When 5.00 mL of a sodium nitrite solution containing 17.04 g/L of sodium nitrite is added to 25.00 mL of sulfamic acid solution containing 2.754 g/L of sulfamic acid, the following reaction occurs:
HSO3NH2 (aq) + NaNO2 (aq) --> N2(g) + NaHSO4 (aq) + H2O (l)
a) Determie the mass of nitrogen gas produced, and calculate the volume occupied by this mass of gas at a temperature of 23 degrees C and a pressure of 00.5 kPa
b) When this experiment was carried out by a student and the nitrogen gas was collected over water, the volume of âwetâ nitrogen produced (at 23°C and 99.5 kPa) was 14.81 mL. What was the percentage yield obtained by the student? The vapour pressure of water at 23°C is 2.81 kPa.
