Stoichiometry and the Ideal Gas Law Results and Discussion: An experiment was carried out involving the reaction between sulfamic acid and a nitrite salt according to the following equation: MNO 2 (aq) + HSO 3 NH 2 (aq) MHSO 4 (aq) + H 2 O(l) + N 2 (g)

where M + is an alkali metal cation: Li + , Na + , K + , or Rb + . The volume, temperature, and pressure of the nitrogen gas produced were measured in order to determine the identity of the unknown nitrite salt. Using these information along with the ideal gas law (PV=nRT), the moles of nitrogen gas produced was calculated. Then, using the moles of nitrogen gas, the moles of MNO 2 was found and along with the mass of MNO 2 sample, the nitrite salt was identified. Before the experiment began, the sample of nitrite salt and the water was weighed. Table 1: Mass Data Nitrite Salt Used (vial #6250) 600 mL beaker 600 mL beaker plus water Water Mass (grams) 0.438 190.092 336.3 146.2 For this experiment, the total pressure in the apparatus was equal to the barometric pressure
