A student plotted the following data to find the density of water: Volume of Water Mass of Water (g) (mL) 9.8231 10.00 12.3465 12.10 14.8999 15.20 20.9875 20.50 26.0020 25.80 After plotting the points on graph paper, the student drew a line best fit and measured the slope. He reported his density of water to be 1 g/ml with 0% error. What should the student have done differently? The student should measure the change in y-values and change in x-values more precisely (with a ruler) to find the slope value. The slope would provide the density of the experimental data, and should be adjusted to the correct number of significant figures. O Nothing should be done differently, the student accurately reported his findings. O The student should graph the points in Microsoft Excel and use linear regression to provide the slope. The slope would provide the density of the experimental data, and should be adjusted to the correct number of significant figures. O The student should average the density values found from each data point and report the findings with 4 significant figures.
