Computation: (12 points) Find a slope from the above graph; then from the slope calculate the value of the gravity. Slope = Ji- y. 9.10- 2.00 7.20 210 - 50 : 0.0450 m 0.0450 871 conggly IM = 8.17 m/q 100 OM 5. Conclusion: (10 points) To error : 9.8 - 8.17 - x 1007, = 10.59. a. 8 The percentage error is above 10% and the only explanation I can think of as to why my experimental value is so off is because depending on where the wine is positioned among the data points, it changes the slope. Since the data points aren't in an actual straight lines, It in a slight challenge to know exactly where to draw the time
