Unformatted text preview: PV= nRT n = 0.012 moles N 2 = 0.012 moles MNO 2 Molar Mass = mass MNO 2 = 0.968 grams MNO 2 = 80.667 grams moles MNO 2 0.012 moles MNO 2 Mass of NO 2 = 46.01 grams 80.667 grams MNO 2 46.01 grams NO 2 = 34.657 grams M M = Potassium [K] The percent error was thus calculated to quantify the accuracy of the results. Percent error = accepted value measured value x 100 = 39.10 grams 34.657 grams x 100 = 11.36% accepted value 39.10 grams Because only one trial was performed, average deviation and relative average deviation values could not be calculated. Therefore, the precision of the experiment was not accounted for. Conclusion The identity of the unknown nitrite salt (M) #2254 is Potassium, K....
