The density of a gaseous compound of phosphorous is 0.943 g/L at 496 K when its pressure is 709 Torr. What is the molar mass of the compound?
On the obtained mass-spectra you got in the expected parent-ion mass region two adjacent lines with almost the same abundance (m/z=258 -100%, and m/z=260 -97%). Fragments do not show any adjacent abundant lines. What conclusion can you derive from..
