Please help! I know the unknown solution is ethanol but need help solving the below equations

Comnlete the followrine tahle 4) Determine the molality (m) of the solution using the following equation Tf=Kfm, where the freezing point depression constant Kf for t-butanol is 8.37C/m. (2 pts) Kfis a constant =8.37 Subtract freezing point of t- butanol From freezing point of t-butanol and unknown mixture 8.373.25=0.388 5) Determine the molar mass of the unknown solute. (molality = moles of solute /kg of solvent).(2 pts) (molality)(kgofsolvent)=molesofsolutemolesofsolutegofsolute=molarmassofsolute 6) Identify the unknown solute. Which of the following possible solutes was the unknown solute? methanol, ethanol or 1-propanol.
