Chapter , Problem 1.6.11(choose chapter or problem)
Students in a chemistry lab are measuring the volume and mass of samples of distilled water and salt water. The results are in Tables 1.39 and 1.40. (a) Make scatter plots of the data, with volume on the horizontal axis. (b) Find the lines of best fit for each data set and graph them together with the scatter plot. (c) What are the units of the slopes of the lines? Interpret the slopes in the context of the problem. (d) What do the slopes tell you about the difference between distilled water and salt water?
