if my molality is 1.08 m and my mass of unknown is 25 g. then how would i find my molecular weight of known.

you don't have to solve it for me. what equation do i have to use

molality depends on mass of solute and mass of the solvent.

molality=masssolute/(molmasssolute*kgsolvent)

so to solve for molmasssolute, you need to know molality, masssolute, and the kg of solvent.
