1. The problem statement, all variables and given/known data a beaker contains 200mL of ethyl alcohol at 20degrees. what is the minumum amount of energy that must be removed to produce solid ethyl alcohol.. the melting/freezing pt is 114degrees Lf=1.09x10^5 density is 790kg/m^3 specific heat cap = 2400J/kgK 2. Relevant equations Q=mcdT Q=ML m=pv 3. The attempt at a solution m=pv=(2.00*10^-4m^3)(790)=0.158kg Q1=mcdT =0.158(2400)(94) =35644.8J Q2=ML =0.158(1.09*10^5) =17222J Qtotal=Q1+Q2 =52866.8J i think i did somethign wrong because in the book it says the answer is 68000J can someone help me out i dont know what i did wrong?
