Search: how many bromine molecules Br2 have a mass equal to 31.8g

Number of results: 4,010

Science
That is not a question. Two molecules cannot occupy the same position. What do you mean by a "similar" position? "a" will be approximately the molecular separation in the solid or liquid state. In the gas phase, there will be some molecules that are colliding.

Well, the Br2 dissolves, and remains in solution as Br2 (unless the presence of a catalyst or strong light, in which it reacts). deltaT=kf*m molality= molesBr/1kg=153/70=2.19 look up kf for Benzene http://hyperphysics.phy-astr.gsu.edu/hbase/tables/bpelev.html
