When 0.500 g of an unknown compound was dissolved in 15.0 g benzene, the freezing point depression was determined to be 0320C. The molar mass of the unknown compound is ?? g/mol.

(The freezing point depression constant for benzene is 5.12C kgmol.

I really don't know where to begin. Can someone provide with some kind of equation so I can solve this?
