Question

How would I find the molar volume of a solute at its boiling point? In the problem I am given:

Carbon tetrachloride at 300K, so how do i find molar volume?

Answer 1

Answer:

If data are not available, the molar volume (V_b) at normal boiling point might be estimated from the following equation:

Where V_critical is the critical volume of CCl₄. The critical volume can be found in reference data or estimated. For example, we do not have these data and will estimate the critical volume by Lydersen method.

, where G_i are increments of functional groups.

Carbon tetrachloride has 4 increments of C-Cl bonds, and each "gives" 49.0 cm³mol^-1:
