The intermolecular potential of methane is given by the following equation: 

With a = 2.05482 × 10⁻²¹ J, σ = 3.786 Å, and r is the distance between molecules (in Å).

a) Make a plot of this potential in the range r = 3 Å to 10 Å 

b) Calculate the distance r* (in Å) where the potential has a minimum. 

c) Estimate the density of liquid methane based on this potential. 

Find the density of liquid methane in a handbook and compare your answer to the tabulated value.
