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

Question

Quizplus · Accepted Answer

The density of sulfur vapor at 1273 K and 740 torr is given, which means the molar mass of sulfur vapor can be calculated. Using the ideal gas law, we can calculate the number of moles of sulfur vapor present in 1 liter of the gas at the given temperature and pressure. This value can be divided by the volume to obtain the density.

The molar mass of sulfur is 32.06 g/mol. Assuming that sulfur vapor is composed of diatomic molecules, the molar mass of sulfur vapor would be 64.12 g/mol. Using this value, the calculated density is 0.5977 g/L, which matches the given value.

Therefore, sulfur at that temperature will be diatomic (B).
