P-Chem: Van der Waals Equation data

[bubbaburp]

Homework Statement

Based on values for the Van der Waals equation tabulated in Table 1.6 in
appendix A, determine an approximate molecular volume for CCl4 and CH4.

Rationalize these values based on reasonable bond lengths and other
parameters. The Lennard-Jones potential energy function is often used to
model interactions between molecules.

Homework Equations

V(r) = 4ε [{σ/R}^12 - {σ/R}^6]

For Cl, ε = 357/k, σ = 4.115 Angstrom
For H, ε = 33.3/k, σ = 2.968 Angstrom

That doesn't count as an effort. Try harder.

C'mon, I'm coming here for help, not to be told how to study. I learn when things are explained to me which, ironically, most of my professors fail to do. At least give me a step forward in the right direction so I can quickly solve the problem. I don't have time for a thorough comprehensive reading on the subject.
