algol [13]

Answer:

52.08grams

Explanation:

Heat of fusion is the energy needed to transform solid water into liquid water. Hess's Law.

The temperature change Liquid water to Solid Ice. 20 degrees C --> 0 degrees C. is 20 degree C.

The heat needed for this  is =  4.184 J/(g*C) * (36 grams of water) * 20 degrees C =  3012 joules of energy.

Liquid water to solid water.

Heat of fusion of water is 335j/g = 6.02kJ/mol

The heat needed for this is 6.02 kJ/mol * 2 moles of water = 12.04 kJ = 12040 joules of energy.

Adding the  two energies, we have a total energy iof 15052 joules.

15052 joules = H(vap of CCl2F2) * grams of CCl2F2 needed = 289 J/g * x grams 15052 / 289 = 52.08 grams needed.
