A solution is made containing 20.6 gg phenol (C6H5OHC6H5OH) in 460 gg ethanol (CH3CH2OHCH3CH2OH).

Calculate the molality of phenol. 

Express the concentration in moles per kilogram to 3 significant figures. 

(i came up with an answer of 0.455  mol/kg but that is wrong). The feedback said: "Incorrect; Try Again; The molality of a solution is the moles of a component per kilogram of solvent rather than per kilogram of solution."

Please help.
