Question -   What is the density of bromine in the solid state? I have
done some checking in handbooks and on the Internet but cannot find it.
-----------------
Dear Robert,

Diatomic bromine has a molar volume of 38.40 cubic meters per Mmol
at 5 deg. Kelvin, according to "Phase Diagrams of the Elements" by David A.
Young
(Univ. of California Press, Berkeley, 1991). The diatomic mass of
bromine is 2*(79.904). From this you should be able to calculate the
density at this temperature. I do not have data for the room temperature
density, sorry.

Best, prof. topper
=====================================================
The melting point of Br2 is 265.9 kelvins. Its density at 123 kelvins is
4050 kg/m^3 = 4.050 gm/cm^3
