how to determine the solubility of BrF5 in water?And what is the explaination according to the polarity?

This again.  OK, first of all, BrF5 reacts explosively with water, so its solubility is a bit of a purely theoretical issue.  If you actually mix BrF5 and water, you get a big bang and no more BrF5.

But in THEORY BrF5 out to be somewhat soluble because the F is substantially more electronegative than the Br, and the structure is square pyramidal, with one F pointing up from a square of four Fs with the Br at the center.   That off-center F will pull electrons toward it, resulting in a dipole moment for the molecule.
