0/10 points A student took data for three trials using a piece of glassware- Density (g/mL) 1.225 1.200 1.180 Deviation (g/mL) 0.023 -0.002 -0.022 Deviation_(g2/mL2) 0.000 529 0.000 004 0.000 484 Pages 1 and 2 in the Experiment #3 handout state the rules for the number of decimal places needed for average, variance, and standard deviation. For questions with dropdown boxes, the editor doesn't allow superscripts in the choices. For example, cm2 would be shown as cm^2 in a dropdown box. The average is X (no answer) X (no answer) Feedback Based on answering incorrectly Watch how you round. Check the experiment handout for the number of decimal places one uses when reporting the average. 7 0/10 points You are given the following data for Experiment #4: 1a. Volume of 3.5 M HCI 1b. Mass of 125 mL Erlenmeyer Flask 1c. Mass of Magnesium Used 1d: Mass of Product and Erlenmeyer Flask 25.00 mL 89.3364g 1.2100 g 96.0984 g The mass of product is X 6.762 g. Watch your decimal places! Feedback Based on answering incorrectly When you subtract to get the mass of the product, make sure you round to the correct number of decimal places. 9 5/ 10 points A student took data for three trials using a piece of glassware- Density (g/mL) 1.344 1.276 1.299 Deviation (g/mL) 0.038 -0.030 -0.007 Deviation?
