We have already investigated the relationship between mass, mole and the number of particles. But, is there any relationship between volume and mass, or mole and number of particles? Lets investigate.
Purpose: Determine if there is a mathematical relationship between the mole and molar volume.
Construct a scatter plot of density versus molar mass for the elements listed below. 

Sketch a simple diagram of the graph into your lab report.
Next, examine the following data for gases and determine if there is a mathematical relationship between the density of a gas and it's molar mass. Do this by constructing a scatter plot of molar mass vs. density. 

Calculate the line of best fits for the graph of Molar Mass (g/mol) vs. Density (g/L) . Record the regression equation in your lab note book and add the regression line to your graph. 

Sketch a simple diagram of the graph into your lab report and record the regression equation.
