1) Dry nitrogen gas (100.0 L) was bubbled through liquidchloroform, CHCl 3, at a given temperature and the evaporatedchloroform condensed; its mass was then measured. Using the databelow, calculate the heat of vaporization (kJ/mol) ofchloroform?
Temperature, °C Mass CHCl3 collected, g
24.07 117.4
38.77 203.5
2) The ionic compound, CsCl, forms a body centered cubicstructure (see below) where the anions occupy the corners of thecrystal (red) and the cations the body centered position (green).If the density of the compound is 3.99g/cm 3 and the ionic radius ofCs + is 169 pm, what is the ionic radius ofCl − in pm?
