Determine the density of the black rubber stopper from the graph _________________
Treatment of Data
1. Using the relation: Density =
mass and y =mx + b, decide how your data should volume
be plotted to get a straight line. (Use mass for the y axis)
2. On a sheet of graph paper, plot your data. ![]()
3. From the graph, calculate the slope and get the intercept.
4. Using the above information, what is the density of the black rubber stopper?
Turn In
1. data: arranged in an organized manner.
