1. The problem statement, all variables and given/known data CHCl3 has M= 119 gmol^-1, density (rho) = 1.48 gcm^-3 Find the average separation between molecules in the liquid assuming a simple cubic packing 2. Relevant equations 3. The attempt at a solution I have found that there are 7.487x10^21 molecules cm^-3. Each molecule "occupies" a box of 133.6 Å^3. Now what should I do? I don't properly understand what they mean by separation.
