Grams P4S7 to molecule Details on molecular weight calculations In chemistry the formula weight is a quantity computed by multiplying the atomic weight in atomic mass units of each element in a chemical formula by the number of atoms of that element present in the formula then adding all of these products together. Easily ignited by friction. Tetraphosphorus Heptasulphide or Phosphorus Tetritaheptasulphide P 4 S 7 was first obtained during the distillation of P 4 S 6 in a vacuum and was separated by heating under pressure with carbon disulphide in which as distinguished from P 4 S 3 it was only sparingly solubleIn the methods of preparation which have been described the phosphorus should.

Phosphorus sulfide P4S7 What information about the compound is not part of a chemical formula.

P4S7 is High Pressure 4-7GPa Tellurium structured and crystallizes in the monoclinic P2_1c space group. Reacts with liquid water or atmospheric moisture to form toxic hydrogen sulfide gas and corrosive phosphoric acid. Phosphorus sesquisulfide free from yellow and white phosphorus appears as a yellow crystalline solid.

Molecular weight of P4S7 or grams This compound is also known as Phosphorus Heptasulfide. All spectra were recorded on a Bruker AC 250 spectrometer operating at 1013 MHz for 31P and the chemical shifts were referenced to 85 D3P04 used as an external standard.
