1) Why is the slope of the line of best fit on a plot of volume (mL) vs. mass (g) a measure of the density for your material?
Homework Answers
The slope of the line is nothing but the measure of (y coordinate/x coordinate) i.e. slope =y/x.
So, in the volume vs mass plot,mass is on y axis and volume is on x axis,so when the slope of the line of best fit is calculated on this plot then it will be y/x=mass/volume which is equal to the density.
As,density = mass/volume.
