Compute the molar mass of the solid the molal freezing

A chemist is specified a white solid that is suspected of being pure cocaine. Define when 1.089 g of the solid is dissolved in 19.93 g of benzene the freezing point is lowered by 1.65 degrees C. Compute the molar mass of the solid. The molal freezing point constant (Ksubscriptf) for benzene is 5.12 degrees C/m.
