Question

When 1.73 kg of ethylene glycol (antifreeze) at 11.6 degrees C are mixed with 1.42 kg of water at 40.4 degrees C, the final temperature is 29.2 degrees C. Find the specific heat capacity of ethylene glycol.

Answer 1

Answer:

I don't know the answer

Answer 2

Answer:

mass of ethylene glycol be xgm

we have freezing point of water as 0 degreeC

depression in freezing in freezing point=0-(-6)=6degreeC

Now depression in freezing point=Kf*m

m is the molality of the solution

m=(x/62)/4=x/248

we have

6=(1.86*x)/248

=800gm
