Unformatted text preview: Divide absolute value of difference between questionable value and nearest neighbor by spread: Q exp = 0.1089 " 0.1072 0.1089 " 0.1061 = 0.61 Find Q in table on page 161: Q 90,5 = 0.64 If Q exp > Q table , then you may reject data. Significant Figures Report all results to FOUR significant figs. Example: M KHP = 7.4307 g 204.23 g/mol 0.2500 l = 0.14553591539 Round off to 0.1455 M Range : Expt. 1 and 2 should be 4 ppt Absolute range = Highest - Lowest Relative Range = Highest - Lowest Average x 1000 ppt Example: Rel. Range = 0.1089 - 0.1061 0.1071 x 1000 = 26 ppt...
