Calculations: 1. Using the data collected in Table 2, construct a plot in Excel according to the directions in your lab handout. Based on this, find the slopes of the trendlines for Ethanol, Methanol, and Acetone: a. Slope (rate of evaporation in units of g/min) of Ethanol: b. Slope (rate of evaporation in units of g/min) of Methanol: c. Slope (rate of evaporation in units of g/min) of Acetone: Format your graph. Make sure there is a graph title and label the axes. Save your data to a flash drive or you may email it to yourself. Ask your instructor whether you need to print your graph or copy/paste your graph into the space below. woy nisipe foonsledures to diaopai 101 Analysis and Discussion: Vesanstase brood 1.
