Question

15) Significant figures in calculations: report two answers digits displayed, an one, with at least 5 Significant hen the answer rounded to the correct number of A c figures (and, of course, display the units) oin weighs 15.79 g and is added to a graduated cylinder with 12.3 ml of water in it, causing the volume to increase to What is the density of the coin?f. units Look up the density of silver, is it possible the coin is silver? 13.8 mL If the balance has an absolute error of +I- 0.01 g what is the relative error of the mass? If the graduated cylinder has an absolute error of +/- 0.1 mL, what is its relative error? Calculate the density by changing the mass by +0.01 g, then -0.01 g, then +0.1mL, then -0.1 mL. +0.01 g g/mL (keep vol const.) -0.01 g- +0.1 mL -0.1 mL What is the minimum? g/mL What is the maximum ? g/mL What is the range/span? (the delta from max to min) ? g/mL Divide that by two and now express the density from the original data with that value and +- (range/2) If you did your original density calculation without making an error in significant g/mL (keep vol const.) g/mL (keep mass const.) g/mL (keep mass const.) g/mL +g/mL figures, then the +/-g/mL should be in the same place as your last significant figure of your density
