Determine the molecular formula of phosphorus.

phosphorus gas has a density of 0.617 g/L at 70 and 200 Celsius ...

  • Chemistry - ,

    * at 790 torr not 70

  • Chemistry - ,

    70 what?
    Use p*molar mass = density*R*T
    Solve for molar mass, then
    molar mass/30.97 = # P atoms/molecule.
