While 5.00mL of a sodium nitrate solution containing 17.04g/L of sodium nitrate is added to 25.00mL of sulfuric acid solution containing 2.754g/L of sulfuric acid, the following reaction occurs:
NaNO2(aq) + HSO3NH2 (aq) →N2 (g) + H2O (l) + NaHSO(aq)
a) Determine the mass of nitrogen gas produced and calculate the volume occupied by this mass of gas at room temperature of 23C.
b) While this experiment was carried out by a student and the nitrogen gas was collected over water, the volume of "wet" nitrogen produced at 23 C and 99.5kPa was 14.81mL. Explain what was the percentage yield obtained? The vapor pressure of water at 23C is 2.81 kPa.
