The density of sulfur vapor at 1273 K and 740 mm Hg is 0.5977 g/L. Sulfur at that temperature will be ________.

Question

Quizplus · Accepted Answer

Sulfur is commonly found as S8 molecules in its solid form, but at high temperatures and low pressures such as in vapor form, the molecules will dissociate into individual sulfur atoms, which will pair up to form diatomic sulfur molecules (S2) due to their tendency to form stable octet structures. Therefore, at 1273 K and 740 mm Hg, sulfur vapor will be diatomic.
