Eugenol, the active ingredient in cloves, has a formula of C10H12O2. What is the boiling point of a solution containing 1.14g of eugenol dissolved in 10.0g of benzene? The boiling point of benzene is 80.1C and the boiling point elevation constant for benzene is 2.53C/m.

I got 180C, but it was wrong also.

delta T = Kb*molality.
You have Kb. molality = moles/kg solvent. You have kg solvent. Moles can be determined by grams eugenol/molar mass eugenol. Then add delta T to 80.1 degrees to obtain the boiling point of the solution.
