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.
