The purpose of the laboratory experiment was to determine the identity of an unknown nitrite salt by using the ideal gas law to measure the moles of N 2 produced in a reaction between the Nitric salt and excess sulfamic acid. Data Unknown Used: #4315 Temperature of the Lab: 22.3˚C Barometric Pressure: 746mmHg Mass (g) 600mL Beaker 184.060 Culture Tube 3.431 Nitrite Salt+ Culture Tube 5.315 Nitrite Salt 1.884 600mL Beaker + Displaced Water 625.7 Displaced Water 551.6 Temperature of Water= Temperature of N 2 = 35.0˚ Calculations Volume of Displaced Water: = Density of Water 1gmL = . ÷ = .
